Trump 2nd term updates: Trump excludes low-value shipments from looming tariffs

Trump said he is still going forward with his threat of tariffs on Mexico and Canada next week because he was not satisfied with their leaders deterring alleged drug trafficking into the U.S.

"And then on, the 2nd of April, we have, reciprocal tariffs. That's reciprocal where we charged countries what they're charging us. And nobody should have a problem with that," he said.

"The United States has been taken advantage of by many, many different countries, including our friends, friend and foe. And in many cases, our friends took bigger advantage of," the president added without giving more details.

Trump said he didn't believe Russia's Vladimir Putin would reinvade Ukraine after the war if the United States didn't provide a "backstop" in the region -- as European nations are pressing for.

Later, he said going through "Russia hoax" with Putin gives him confidence he can trust Russian leader as negotiations unfold.

"I think he'll keep his word," Trump said.

Trump reiterated his plans to issue tariffs on European countries over what he claimed were unfair economic practices against the U.S.

When asked about possible sanctions against the U.K., Trump said, "well I have to take a look. I mean, we're going to have a good discussion today and we have some very talented people on the other side."

Trump was asked about tracking the number of veterans who have been fired from federal agencies, and said he is watching it carefully

"We hope it's going to be a smaller number as possible. But we are having great success in slimming down our government," he said.
