Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

SoftBank CEO Masayoshi Son, OpenAI's Sam Altman and Oracle's Larry Ellison are expected to be at the White House Tuesday afternoon, according to a source familiar with the matter.

President Trump is set to announce $500 billion in private sector investment to build artificial intelligence infrastructure. It's a joint venture of three companies -- OpenAI, Softbank and Oracle -- collectively called Stargate.

Last month, Trump announced with SoftBank's Son in Mar-a-Lago that SoftBank would invest $100 billion in US projects over the next four years, creating 100,000 jobs. Those investments will focus on infrastructure that supports AI, including data centers, energy generation, and chips, according to a source.

The new announcement Tuesday has "overlap" with SoftBank's previous commitment of $100 billion, according to a source, who clarifies that this is not an entirely separate commitment.

While the Trump team had a flurry of executive actions ready to go within minutes of the president being sworn in, behind the scenes staff are still unpacking and getting accustomed to their new surroundings.

Staffers are buzzing about, unpacking, and trying to get their email up and running. The press email system is still a work in progress.

While the Oval Office was quickly transformed back to Trump's liking, members of his administration are now moving around their own office furniture and pondering what to put in the empty frames that sit askew on their walls.

One thing that was quick to turn over -- the "jumbos," the large glossy official photographs of the president that line the west wing hallways.The Trump team has already put up framed images of yesterday's inauguration.

President Donald Trump's first sit-down interview of his second term will be with Fox's Sean Hannity in the Oval Office.

It will air on Wednesday at 9 p.m. ET, the network announced.

During the interview, Trump will "discuss the executive orders he's signed thus far, his first 100 days in office and news of the day," according to the release from the news channel.

During his first term, Trump sat down with ABC News' David Muir for his first interview. That interview took place just five days after he was sworn into office in 2017.

Tariffs were not in the executive orders Trump signed on Monday night and he suggested he’s still undecided on how far they might go -- which investors are reading as a good sign, reflected by the rallying market on Tuesday.

Trump said he was now targeting Feb. 1 as a potential target date for tariffs to take effect against Mexico and Canada, which he said could be as high as 25%. He said any plans for blanket tariffs are “not ready” just yet.

Trump has a history of using the threat of tariffs as a governing style.

Urging Mexico to crack down on border crossings in 2019, Trump threatened to slap a tariff on the country within 10 days through the International Emergency Economic Powers Act (IEEPA) but relented after Mexico committed to specific measures.
