Trump did not provide any timing on when Alexander is expected to be released.
The White House said on Sunday that it reached a trade deal with China as the two countries negotiated for a second day in Switzerland. China has yet to comment on Sunday's talks.
"We’re confident that the deal we struck with our Chinese partners will help us to work toward resolving that national emergency,” U.S. Trade Representative Jamieson Greer told reporters in Geneva. But Treasury Secretary Scott Bessent said "substantial progress" had been made but stopped short of touting a full deal.
On Thursday, President Donald Trump announced a trade deal with the United Kingdom -- the first in what the White House said it hopes will be a flurry of agreements while the reciprocal tariff pause is in effect. With UK Prime Minister Keir Starmer on speaker phone in the Oval Office, the leaders conceded that they are still working out the details of the agreement.
Trump congratulated the new pope in a Truth Social post.
"It is such an honor to realize that he is the first American Pope. What excitement, and what a Great Honor for our Country. I look forward to meeting Pope Leo XIV. It will be a very meaningful moment!" he said.

The British Prime Minister's office gave more details on its trade deal.
Under the agreement, American tariffs on British cars reduce from 27.5% to 10% for the first 100,000 vehicles exported from the U.K. to the U.S., while tariffs on steel and aluminum are dropped altogether.
"We are the first country to secure such a deal with the United States," Starmer said in remarks from a Jaguar Land Rover plant in the West Midlands region of England.

Trump said he will announce a new nominee for the U.S. Attorney for the District of Columbia.
His original pick, acting attorney general Ed Martin, lost support from Republicans over several controversies including Martin's constant defense of Jan. 6 rioters.
"He is a terrific person. He wasn't getting the support from people that I thought," Trump said.
"I'm very disappointed in that. But I have so many different things that I'm doing now with the trade. One person, I can only lift that little phone so many times in a day. But we have somebody else that will be great," the president added.
Peter Mandelson, the British ambassador to the U.S., told reporters that the U.K. is committed to "reducing tariffs and non-tariff barriers."
"This is a continuing picture, it is a movie, not a still picture. A movie, it continues. We're both committed to freeing up trade between our countries," he said.
"The point about this deal is that it provides very good template and very good launch pad for what we can continue to do and build on in the future," Mandelson added.
