April 29 marks day 100 of Donald Trump's extraordinarily eventful second term as US president. Here's some of what you might have missed.
Day one: Rioters are released from prison
One of Trump's first Oval Office orders was to release supporters who'd been jailed over the US Capitol riot of January 6, 2021. Trump told prison authorities to pardon almost 1,500 people, and commute the sentences of 14 others so they could be freed straight away.
Trump said they'd been treated unfairly compared to other criminals. "Murderers today are not even charged," he said.
"These people have already served years in prison and they've served them viciously."
Supporters quickly gathered outside the Washington jail where the prisoners were being held. Damien Rodriguez — who was at the Capitol on January 6 but not charged — was among them. "I feel very happy for the families that are getting their political prisoners back," he told the ABC.
The pardoned rioters included a group of men who bashed and repeatedly tasered police officer Michael Fanone. He told us he felt betrayed by his country. "The American people chose Donald Trump to be their president after he promised to pardon these individuals," he said. "These violent, vicious criminals who attacked cops for doing nothing more than their job."
Day three: Troops are deployed to the Mexican border
Two days after Donald Trump declared a national emergency at the southern border (having also done this in his first term), the US military began deploying thousands of troops there.
In an executive order, the president said "cartels" and "criminal gangs" had overrun the border.
"America's sovereignty is under attack."
The initial deployment of 1,500 troops has since swelled to close to 7,000 marines and soldiers.
The crackdown has seen illegal border crossings grind to a halt, hitting their lowest levels in decades.
The number of migrants trying to cross the border from Mexico had already started to come down towards the end of the Biden presidency. But Trump's moves, which also included indefinitely halting asylum for anyone coming through the southern border, had a dramatic impact.
Unauthorised border crossings fell from a record high of 250,000 in December 2023 to just over 7,000 in March, according to official figures.
Day 11: Trump blames diversity initiatives for a plane crash
Less than a fortnight into his second term, the president was tasked with leading the nation through its deadliest plane crash in nearly 25 years.
A commercial aircraft and a Black Hawk helicopter collided midair, killing all 67 people on board the plane as it plunged into the icy Potomac River in Washington DC.
The next day, at a press conference, Trump attacked previous Democratic administrations and speculated that diversity, equity and inclusion (DEI) policies were to blame for the collision.
Asked how he could suggest this without evidence, Trump replied:
"Because I have common sense."
"I think it's disrespectful to the families," former air traffic controller Todd Yeary told 7.30. "Even while he was making that comment, the air traffic control system was working around his head while he was saying it."
Trump's focus on stripping away DEI policies had been made evident on day one, when he signed an executive order to remove all relevant programs across the entire federal government.
It was one of several executive orders he has signed to dismantle the programs he says hinder a merit-based hiring process.
The administration also ordered employees of federal DEI and accessibility offices to be put on paid administrative leave.
Some of America's biggest companies, such as Meta and McDonalds, have also reversed or scaled back their diversity and inclusivity programs to align more with the Trump administration's ideology.
Day 15: Foreign aid staff are told not to come to work
Foreign aid was one of the first big targets of the "Department of Government Efficiency" (DOGE) — the Elon Musk-led team tasked with shrinking government and rooting out "waste and fraud".
Under Donald Trump's orders, DOGE quickly moved to gut the US Agency for International Development (USAID), cancelling more than 80 per cent of its programs and telling most of its staff they were being fired.
Workers were locked out of email and computer systems and told not to come back to work.
It created chaos for aid agencies abroad. "Everyone's scrambling trying to work what this means," Josie Pagani, CEO of charity ChildFund New Zealand, said in the subsequent days.
Trump labelled USAID a "left-wing scam".
"We're giving billions and billions of dollars to countries that hate us."
Smaller foreign aid agencies were also later targeted.
Day 16: Trump says the US should take over Gaza
Throughout last year's election campaign, Trump vowed to bring lasting peace to the Middle East.
When he met Israeli Prime Minister Benjamin Netanyahu in February, he floated a brazen and controversial vision for how he might do that.
The president declared the US should seize control of Gaza, permanently displace the Palestinian population, and ultimately turn the devastated seaside enclave into "the Riviera of the Middle East".
"The US will take over the Gaza Strip, and we will do a job with it, too.
"Everybody I have spoken to loves the idea of the United States owning that piece of land, developing and creating thousands of jobs with something that will be magnificent."
Unsurprisingly, Netanyahu welcomed the president's "fresh ideas", but elsewhere, they led to shock and condemnation, including from countries across the Middle East and the United Nations.
Both Jordan and Egypt — which Trump proposed would accept the approximately 2 million displaced Palestinians — rejected the idea, which is also illegal under international law.
Gazans voiced their opposition to the ABC. "This project will fail," one said. "If the people wanted to leave Gaza they would have left before, currently they can't, all the people would rather die in Gaza than leave."
Trump's comments came during a delicate ceasefire which his Middle East envoy Steve Witkoff had helped broker.
After six weeks, Israel started heavily bombing Gaza once again, shattering hopes for an extension of the ceasefire.
Day 40: Trump and Vance berate the Ukrainian president
During the first month of his presidency, Trump repeatedly criticised Ukrainian President Volodymyr Zelenskyy and praised Russian President Vladimir Putin.
Trump falsely claimed Ukraine invaded Russia, and called Zelenskyy a "dictator."
Despite the public attacks, it appeared there was movement on a deal under which Ukraine would share critical mineral deposits with the US in exchange for ongoing military help.
Zelenskyy was invited to the White House to sign the deal, but the picture opportunity turned into a globally broadcast nightmare for the Ukrainian.
Vice-President JD Vance accused Zelenskyy of showing insufficient gratitude to America, and Trump fired up after Zelenskyy suggested the US could feel the effects of Russian aggression.
"Don't tell us what we're going to feel because you're in no position to dictate that," Trump said.
"You're gambling with World War III."
Zelenskyy was whisked out of the White House before lunch was served. The deal was not signed and, in the following days, the US temporarily suspended military aid and intelligence sharing with the war-torn nation.
"It's absolutely unprecedented to have a head of state come to the Oval Office and be berated in such a personal way," Ohio State University historian Christopher McKnight Nichols told the ABC afterwards.
Left with little choice, Ukraine later agreed to an American proposal for a 30-day ceasefire. Trump spoke to Putin by phone, but Russia would not agree to the same terms.
The US is continuing efforts to broker a deal, but Trump has warned the US could give up if there's no meaningful progress soon.
Day 53: A journalist is added to a group chat about military plans
When defence secretary Pete Hegseth shared attack plans in Yemen with colleagues via a chat app, he didn't realise a reporter had also been added to the chat.
Jeffrey Goldberg of the Atlantic had been inadvertently looped in by national security adviser Michael Waltz.
He then reported what was shared, triggering one of the Trump cabinet's biggest scandals.
Many national security experts said the information — including bombing targets and timings — clearly should have been classified and more carefully handled in line with protocols.
Trump pushed back on pressure to discipline Waltz or Hegseth, saying:
"It's all a witch-hunt."
The Pentagon's chief spokesman, John Ullyot, later resigned and wrote that the scandal was the start of "a month of total chaos" at the Pentagon. Several top advisers and managers left the agency in what Ullyot called "a strange and baffling purge".
The New York Times later reported Hegseth had posted essentially the same attack plans in a second group chat, which included his wife, brother and personal lawyer. Hegseth blamed disgruntled former employees for leaking against him.
The Pentagon's spokesman, Sean Parnell, has argued there "was no classified information in any Signal chat, no matter how many ways they try to write the story".
Day 55: Hundreds of migrants are flown to a Salvadoran jail
Donald Trump campaigned on the promise of implementing "the largest domestic deportation operation in American history" and he didn't waste any time getting started.
A day after invoking a rarely used wartime law, the Trump administration deported hundreds of Venezuelan migrants to a notorious prison in El Salvador.
The government said all the men were members of a foreign "terrorist" gang, and therefore did not deserve due process. Trump said they went through a "strong vetting process".
"This was a bad group, and they were in bad areas."
But court documents suggest officials were able to rely on tattoos, clothing and social media posts as proof of gang membership.
Family members and advocates say this resulted in innocent men being targeted.
One for example was a gay makeup artist fleeing persecution, whose lawyer argues he was jailed because of "mom" and "dad" tattoos on his arms.
The deportations set off an ongoing legal stoush and ignited fears of a constitutional crisis.
A federal judge tried to block the deportations and later found the government showed "wilful disregard" for his order.
Another high-profile deportation case — that of Maryland father Kilmar Abrego Garcia — has been at the centre of a separate court fight.
The 29-year-old was sent to the Salvadoran jail despite a 2019 court order to protect him from being returned to his home country.
The government admitted the deportation was an "administrative error" but the Trump administration has since argued it's powerless to bring him back.
The Supreme Court ruled the White House must facilitate his return but a lower court has slammed it for doing "nothing" to retrieve him.
Undeterred, Trump has doubled down on his deportation blitz, even suggesting he'd like to send US citizens to prisons in El Salvador in the future.
Day 73: Trump unveils tariffs for 185 countries
Donald Trump started introducing new tariffs early in his presidency, but his "Liberation Day" announcement promised to be the motherlode.
In the White House's Rose Garden, flanked by a myriad of American flags, he announced an astonishing change to American economic policy, saying:
"For decades, our country has been looted, pillaged, raped and plundered."
Using what turned out to be a crude calculation based on current trade levels, he revealed the punishments for a long list of countries he said were ripping off America — tariffs of up to 49 per cent.
Over the coming week, markets see-sawed furiously.
Then, amid a major sell-off on the all-important bond market, Trump made an about-face. He paused the country-specific "reciprocal" tariffs for 90 days, but the 10 per cent "baseline" remains in place.
The tariff on China though eventually settled at 145 per cent after back-and-forth retaliation between the world's two biggest economies.
Day 85: Trump freezes billions in Harvard University funds
Harvard, America's oldest and richest university, has found itself at the frontline of a fight between the Trump administration and higher education across America.
Trump accuses universities of pushing left-wing and "woke" ideals, and of mishandling pro-Palestinian campus protests.
His administration has made demands that many universities have agreed to under threat of funding cuts.
But Harvard refused to bow to the orders — which included cancelling diversity-based admissions and hiring initiatives, overhauling leadership, banning face masks and increasing campus policing.
So Trump froze billions of dollars in Harvard funding, declaring:
"Harvard is a joke, teaches hate and stupidity, and should no longer receive federal funds."
At the time, Harvard law professor Andrew Crespo said Trump "wants to change what we're teaching."
"He wants to make sure we're only asking questions that he wants to ask and giving the answers that he wants to be giving," he told the ABC.
Trump has also threatened to revoke Harvard's tax-exemption status and block it from enrolling international students. Harvard is now suing.
The White House is investigating Harvard and 59 other universities for alleged antisemitism, including Ivy League schools Cornell, Princeton and Brown, which have all had funding threatened or suspended.
Day 93: Elon Musk says he'll step back from DOGE
The work of the world's richest man as Trump's chief cost-cutter has made him one of America's most polarising figures.
Opponents have targeted his companies — particularly car-maker Tesla — with protests, boycotts and even vandalism.
After Tesla reported a massive fall in profits, Elon Musk said his time spent working with DOGE would "drop significantly".
Trump called the public backlash unfair.
"Everything he does is good, but they took it out on Tesla."
DOGE says it has saved taxpayers more than $US150 billion — much of it characterised as "waste and fraud" — but many of its published "receipts" have been disputed after independent analysis. Some cuts — such as to nuclear weapons workers — were hastily reversed.
A Reuters tally found 260,000 public servants had lost their jobs.
Among the most controversial cuts have been the firings of thousands of health workers, and the freezing of hundreds of science and medical research projects that were already underway.
