He headed to the new military immigration enforcement area without reporters.
A federal judge ordered a Venezuelan couple, accused by the Trump administration of being members of the Tren de Aragua gang, to be released, delivering a stinging rebuke of the government's evidence in the case.
Earlier this week, Defense Secretary Pete Hegseth on Friday was making an announced trip to the southern border -- without reporters -- as he faces new scrutiny in Washington.
ABC News has confirmed that, in at least two separate meetings, Hegseth accused top-ranking military officers of leaking to the news media and threatened to polygraph them.
Hegseth also used the Signal app on a personal computer in his office that was connected to the internet on an unsecured commercial line, what's known as a "dirty line," two sources confirmed to ABC News Thursday. A Pentagon spokesman called that report "fake news."
Trump was asked about what concessions the Russian government has offered to reach a peace plan with Ukraine.
The president gave vague details.
"Stopping the war, stopping taking the whole country," he said. "Pretty big concession."
Trump was asked about the latest Russian attacks on Ukraine and what he was doing in response.
The president claimed that he was putting a lot of pressure on Russia and that he was not happy with Putin.
"You have no idea what pressure we're putting on Russia," Trump claimed.
President Donald Trump's online store released a 'TRUMP 2028' hat on Thursday after teasing that he could run for president in 2028.
Trump previously addressed speculation about running again in a March phone call with NBC News and said he is "not joking" about a third term, adding, "It is far too early to think about it."
But when asked whether he has been presented with plans to allow him to seek a third term, Trump said, "There are methods which you could do it."
The Constitution's 22nd Amendment states that no one can serve as president for more than two four-year terms.
Democrats seized on the release, posting on their rapid response X account that the hat seems to confirm "his fourth run for president."

President Donald Trump was asked Thursday if he believes Russian President Vladimir Putin is "serious" about wanting peace after deadly strikes on Kyiv this week.
"So we are thinking that, very strongly, that they both want peace, but they have to get to the table," Trump said as he held a lunch with Norwegian Prime Minister Jonas Store. "We're waiting a long time. They have to get them to the table. And I think we're going to get peace."
Trump added there is a "lot of very bad blood" but that he hopes the two nations will come to an agreement.
Asked if he has a deadline for peace talks, after warnings that the United States could walk away from negotiations, Trump said he has his "own deadline" but didn't elaborate.
"I have my own deadline, and we want it to be fast. And the prime minister is helping us. He wants it to be fast, too," he said. "And I think everybody in this, you know, at this time in NATO, they want to see this thing happen. So, we have a deadline. And after that, we have a -- we're going to have a very much different attitude. But I think it has a very good chance of getting done."
