The rare appearance comes as the president faces extraordinary pushback from America's European allies over his planned tariffs over Greenland, tensions he'll confront in person this week at the World Economic Forum in Davos, Switzerland.

European Commission President Ursula von der Leyen described Trump's planned new tariffs over Greenland as "a mistake especially between long-standing allies" and called into question Trump's trustworthiness, saying that he had agreed last year not to impose more tariffs on members of the bloc.

Trump announced that starting February, a 10% import tax will be imposed on goods from eight European nations that have rallied around Denmark in the wake of his stepped up calls for the United States to take over the semi-autonomous Danish territory of Greenland.

Entering the briefing room with a thick stack of papers, Trump said that he had in his first year back in the White House had "done more than any other administration has done by far."

"It's been an amazing period of time," Trump said, thumbing through the pages.

Trump addressed reporters alone at the podium, with White House press secretary Karoline Leavitt standing off to his right. He quickly launched into holding up photographs of people arrested in Minnesota, with each saying "Minnesota worst of the worst."

As he continued to show mugshots of those he described as "rough" people arrested during federal agents immigration enforcement surge in Minnesota, Trump also linked the fraud allegations in the state to its Somali community, which he has also done in the past.

"I'm going through this because I think we have plenty of time," Trump said, alternating between discussing Minnesota and other issues, including his impending trip to the World Economic Forum in Davos, Switzerland.

Trump's administration has urged a judge to reject efforts by Minnesota and its largest cities to stop the surge, calling the lawsuit — filed soon after the fatal shooting of Renee Good by an immigration officer — "legally frivolous."
