Trump admin live updates: Trump says Hamas will release hostage Edan Alexander

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.

Trump was asked about negotiations with China over the tariffs and claimed that the Chinese government has been taking away many of America's industries such as microchips.

"I would like to say they can do better in terms of the bottom line. We would like to see China opened up so we can compete in China and give people something that they've never had," he said.

"Access to something that would be great for the world and great for our businesses and I think it would be great for friendship," he added.

Trump credited Brexit for helping to get the tentative deal with the U.K. and bashed the European Union.

"We intend to make a deal with Europe. We have found that the European Union treated us extremely unfairly. They are very difficult, and hurt themselves in doing so and very much want to make a deal. We're dealing with them currently," he said.
