Trump 2nd term live updates: More executive action plans for Day 2

During his AI infrastructure announcement, Trump threatened to impose tariffs on the European Union, as he has done with Canada, China and Mexico.

"It's not just China. China is an abuser, but the European Union is very, very bad to us," Trump told reporters after the announcement. "They treat us very, very badly. They don't take our cars. They don't take our cars at all. They don't take our farm products. Essentially, they don't take very much. We have a $350 billion deficit with the European Union."

"They treat us very, very badly, so they're going to be in for tariffs."

Trump said Biden gave a "very nice letter" before he left office and that he appreciated it.

"It was an inspirational-type letter," he said. "Do a good job. Important, very important how important the job is."

Trump said he is eyeing Feb. 1 as the date to start implementing his tariffs on China and Mexico.

Trump was asked about pardoning the Jan. 6 rioters during a news conference Tuesday and dodged a question about pardoning violent Jan. 6 convicts, including one who admitted to attacking an officer.

The president dodged the question, claiming he would look into it, before changing the subject to murders around the country that he claimed yielded no arrests.

He repeated his claim that the people pardoned were unjustly prosecuted, including the head of the Proud Boys and the Oath Keepers.

"The cases that we looked at, these were people that actually love our country, so we thought a pardon would be appropriate," he said.

Trump was asked about the pardons again, as well as Vice President J.D. Vance's statement last week in which he opposed pardoning rioters who assaulted officers, but the president again claimed the rioters were unfavorably treated.
