Trump is on camera now in the Oval Office signing a series of executive orders.
He has just signed one on Artificial Intelligence and another on cryptocurrency.
"You might not find them exciting but we're going to make a lot of money for the country," he says after signing the crypto order, which would create a working group focused on making the US the "crypto capital" of the world.
We're beginning to get some detail through now on the executive orders Donald Trump is signing today at the White House.
It's still unclear exactly how many he's planning to sign in total, but, according to the Reuters and AFP news agencies, he has so far signed the following:
We'll bring you more details on these orders shortly, in addition to any more signed.
In the past few minutes President Donald Trump has been signing a number of orders, back-to-back.
Among those he is signing in the Oval Office is a pardon for 23 anti-abortion protesters.
We will bring you more updates on this shortly.
Earlier today, a federal judge temporarily blocked Trump's executive order denying birthright citizenship to the children of undocumented people or those in the US temporarily.
Now, Trump says his administration will appeal the ruling.
"Obviously we will appeal it," Trump told reporters, according to Agence France Presse.
As we learn more details, we'll bring them to you.
The US Senate has just advanced Pete Hegseth's nomination for defense secretary, and the full chamber is now set to vote on it tomorrow.
He only needs to receive a simple majority in the 100-seat Senate to be confirmed. Republicans hold 53 seats, and so far only two have indicated they will not vote for him, which means he is currently on track to approval. Vice-President JD Vance would cast the deciding vote if there is a tie.
We're hearing about another Republican who could vote against Pete Hegseth becoming the next defense secretary - Maine Senator Susan Collins.
She also voted against moving his nomination out of committee and to the full Senate for approval.
We told you earlier, external about Alaska Senator Lisa Murkowski saying she'd vote against him when the chamber takes up his nomination, now expected to happen later on Friday.
Hegseth only needs a simple majority to win confirmation. That means that if all Democrats vote against him, he would only be able to lose four Republican votes. With only Murkowski and Collins saying they intend to vote against him, it currently appears he's on track to become the next defense secretary.

The visit comes after President Trump said in his inaugural address that wants to “take back” the Panama Canal, a statement that has been rejected by Panama’s government.
Rubio's spokeswoman Tammy Bruce said the trip to South and Central American neighbours was intended to show the US wanted to be “safe and prosperous and in good shape”.
"There's a reason why this is the first trip," Bruce said. "It signals how seriously he takes it, what it's going to mean when it comes to his programs, and how it relates to his commitment to this nation, to address those issues that matter to him, and certainly the issues of the Trump agenda."
Before and after his inauguration, Trump said he wanted to “take back” the Panama Canal, claiming it was being operated by China. It is in fact owned and operated by the Panamanian government, although China has invested heavily in ports and terminals near the canal.
Panama President José Raúl Mulino has said the canal is and will remain Panama’s.

US military operations on the border will begin in the next 24 to 48 hours, according to senior defence officials.
According to the officials, an initial deployment of 1,500 troops - 1,000 from the Army and 500 Marines - will be to San Diego, California, and El Paso, Texas. Some of the troops were previously involved with combatting wildfires in California.
Separately, four large transport aircraft - including two massive C-17s - are being prepared for deportation flights.
None of the forces will be involved in law enforcement efforts, and instead will be involved in constructing "physical barriers" and other missions, including intelligence gathering.
It is unclear if any of the troops will be armed, but Pentagon officials have noted that military forces deployed to the southern border have, in the past, occasionally been armed when it is deemed the security situation warrants that.
The injunction blocking Trump's executive order to restrict birthright citizenship is only temporary.
Should the measure go through, hundreds of thousands of families could soon be affected.
The order applies to children born to parents who are undocumented migrants or in the country temporarily.
There were 255,000 children born to undocumented mothers in the US in 2022, according to the legal challenge from the state of Washington and three others that was just heard in court in Seattle.
Over time, the number affected could multiply into the millions, according to a study done by the Migration Policy Institute and Pennsylvania State University.
"Under a scenario denying U.S. citizenship to babies with one parent who is unauthorized, our analysis finds that the unauthorized population would balloon to 24 million in 2050 from the 11 million today," the Migration Policy Institute said.
We'll be turning our attention to the White House soon, where President Donald Trump is shortly expected to sign another executive order.
What the contents of that order will be - and if he will sign more than one - is not yet known.
We'll fill you in on the details as soon as we have them.

This executive order was always going to hit a snag for President Trump.
Birthright citizenship has been a part of the US Constitution since 1868, automatically making nearly anyone born within the US or its territories a citizen.
Trump issued this order within hours of becoming president, declaring any baby born to undocumented immigrants would not be a citizen of the US. It also extended to parents who are in the country legally but temporarily - such as tourists, students and workers.
Rights groups and more than 20 Democratic-led states filed a lawsuit to get it blocked.
A federal judge said the order was "blatantly unconstitutional” and has temporarily blocked it from taking effect next month, issuing a two-week restraining order.
This could eventually reach the Supreme Court, which would have to agree to take the case.
But given the court has a conservative supermajority, those who support the executive order hope the justices would allow it to go into effect.

We're pivoting momentarily to the Senate confirmation of Donald Trump's pick for Secretary of Defense, Pete Hegseth.
Republican Senator Lisa Murkowski of Alaska has released a long statement this afternoon saying she "cannot in good conscience" support him for the post.
This makes her the first Republican to oppose President Trump's pick.
The full Senate is scheduled to vote on confirming Hegseth later today. He only needs a simple majority in the 100-seat Senate to be confirmed. Republicans hold 53 seats, which means he could still become the next secretary even after losing Murkowski's support.
Hegseth, a former Fox News host and Army veteran, has faced numerous allegations of abuse and misconduct since Trump put his name forward for the post. Most recently, his ex-sister-in-law accused him in a sworn affidavit to Congress of alcohol abuse and threatening the safety of his ex-wife. Hegseth has consistently denied criminal allegations, and has sought to reassure lawmakers he does not plan to drink alcohol if he serves as secretary.
Murkowski says she commends Hegseth's service to the country, but worries about comments he made earlier - and has since revised - that women should not be allowed to serve in combat.
She adds that past behaviours Hegseth has admitted to, including marital infidelity on multiple occasions, "demonstrate a lack of judgement that is unbecoming of someone who would lead our armed forces."

Nicholas Brown, the attorney general for Washington state, tells BBC News that of all the presidential orders issued by Trump that the state dislikes, the order restricting birthright citizenship was the first one it decided to fight, “because this case is getting at what it means to be an American."
“It’s getting at how do you define citizenry in the United States. It has a tremendous impact on the hundreds of thousands of babies that are going to be born this year.” He also tells me that he has no concerns about potential retaliation from the federal government.
As we explained earlier, for more than 125 years, nearly anyone born on US soil has been given citizenship, regardless of their parents' immigration status.
But many have criticised the practice, arguing that it is a "great magnet for illegal immigration".
Lawyers for President Donald Trump have argued that the 14th Amendment should be interpreted differently.
Specifically, they say that there is language in the amendment that means it should not be applied to children of those who are unlawfully in the US, or on temporary visas. That section reads: "and subject to the jurisdiction thereof."
Some states and civil right groups, however, disagree with that interpretation and say denying birthright citizenship is unconstitutional.

In Seattle, lawyers for the four states are now speaking to the press about the temporary block of Trump's executive order on birthright citizenship.
"This was fairly obvious. This was simple," says Nicholas Brown the attorney general of Washington, speaking about the judge's decision.
He says the nationwide block is just the first step, but predicts that it won't be overturned by another court.
We are waiting to hear what the Trump administration's next legal move will be.

Birthright citizenship, where anyone born on US soil is automatically granted citizenship, was not originally part of the US constitution, but added decades after the country was founded.
How did it come to be? And what has it meant in practice?
The 14th Amendment was adopted in 1868, after the Civil War ended. The 13th Amendment had abolished slavery, while the 14th settled the question of citizenship of freed, American-born former slaves.
The amendment reads: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside."
The last time there was a dispute about what the amendment means was more than a century ago. In 1898, the US Supreme Court affirmed that birthright citizenship applies to the children of immigrants in the case of Wong Kim Ark v United States.
Courts have not re-examined the issue since and for the last 127 years, the US has granted citizenship to nearly anyone born on US soil, regardless of their parents' status (the few exceptions include children of foreign diplomats).

Things did not go well for Trump’s lawyers during the brief hearing in Seattle, where four states asked a judge to immediately block Trump’s attempt to deny the right to birthright citizenship to children born to undocumented migrants and people in the US temporarily.
Just as Justice Department lawyer Brett Shumate began his arguments on the validity of the order, Judge John Coughenour cut in, asking him point blank: “Is this order constitutional?”
The judge again interrupted as Shumate began to respond, saying: “This is a blatantly unconstitutional order.”
“We look back in history and say ‘where were the judges, where were the lawyers?’”, the judge continued. “Frankly I have difficulty finding that a member of the bar can state confidently that this is a constitutional order.”
The "bar" refers to the American legal professional institution.

There are a few stoney faces as delegates leave the hall following the speech Trump just delivered virtually here in Davos, but some happy ones too.
“A very powerful speech” says one audience member.
“I liked it, I thought it was really good” says another, a delegate from the US. “A lot of it made sense. Common sense. He’s just looking for fair trade."
One Swiss executive, though, is pretty downbeat.
“It’s nothing new, but it’s clear what he wants to do”, he says. “Am I happy? No I’m not happy. I think it’s bad for the world."
