US President Donald Trump said Tuesday that federal agents "make mistakes sometimes" in enforcing his immigration crackdown, an acknowledgment that comes after weeks of violent confrontations - including the fatal shooting of Renee Nicole Good - in the streets of Minneapolis.

"ICE is going to be too rough with somebody, or, you know, they`re dealing with rough people," Trump said of Immigration and Customs Enforcement officers during a lengthy White House press room briefing focused mostly on highlighting the milestones of the first year of his second presidency.

"They`re going to make some mistakes sometimes," he said. "It can happen. We feel terribly."

Trump`s rare appearance at the press briefing marked one year since his inauguration. He expressed exasperation that Americans have been more focused on clashes between immigration agents and the public than on allegations that members of Minnesota`s Somali American community have participated in schemes to defraud the government.

It was one of many subjects on which his frustration - directed at everyone from the media to world leaders to his own communications team - bubbled to the surface during more than an hour of uninterrupted remarks followed by a question-and-answer session with reporters.

Trump also spoke specifically of Good, who was shot by ICE officer Jonathan Ross on Jan. 7, after Ross and other officers approached her stopped car and she began to drive.

"I felt horribly when I was told that the young woman, who was - had the tragedy," he said, adding that he heard her father was a Trump supporter. "It`s a tragedy. It`s a horrible thing. Everybody would say it. ICE would say the same thing."

In an interview with The New York Times hours after the shooting, Trump appeared to blame Good for her own death, citing video that he said showed Good was trying to hit Ross with her car.

"She behaved horribly," Trump told the Times. "And then she ran him over. She didn`t try to run him over. She ran him over."

His social media post hours after the shooting also claimed Good "violently, willfully, and viciously ran over the ICE Officer."

Videos from that day contradict his version of events.

On his Truth Social platform Tuesday, Trump also lamented that the Department of Homeland Security and ICE weren`t getting enough support, saying they needed to talk more about the "murderers and other criminals that they are capturing."

Trump started his briefing room appearance by noting that he believes he`s not getting enough credit on the economy, an issue where polls show the American public has lost faith in his leadership.

"Maybe I have bad public relations people," he said from the lectern where White House press secretary Karoline Leavitt normally addresses the media. "I think we`re doing a much better job than we`re able to promote. We`re not promoting. ... It`s one of the reasons I`m doing this news conference."

Trump, who listed economic data points to argue that Americans are prospering under his leadership, said he does not believe he is repeating the error of his predecessor, President Joe Biden, who touted economic accomplishments when many voters felt squeezed by prices.

"No, I hope I don`t make the same mistakes as him," Trump said.

The president spoke at length about foreign policy, giving a virtual tour of a globe that he hopes to remake and lamenting, again, that he did not win a Nobel Peace Prize for work done in his first year back in the White House. He said he believed he should have received the prize for "each war" that he`s ended; Trump has claimed that he has ended eight wars.

When pressed by a reporter about how winning the Nobel Peace Prize would help "everyday Americans," Trump acknowledged it wouldn`t.

"What improved the lives of people are people that are living. I saved probably tens of millions of lives in the wars," he claimed.

He kept heat on European allies who oppose his plan to acquire Greenland, which belongs to Denmark, by purchase or force. Asked how far he would go to take the island, Trump replied: "You`ll find out."

He blamed Norway for the Nobel Peace Prize snub, contending that the government in Oslo bestows the award - even though it doesn`t.

"I lost a lot of respect for Norway," he said. "I believe very strongly that Norway controls the Nobel Prize."

At the same time, he offered both an olive branch and a prod to European officials in affirming that he intends to protect North Atlantic Treaty Organization allies from external threats.

"The big fear I have with NATO is we spend tremendous amounts of money with NATO, and I know we`ll come to their rescue, but I just really do question whether or not they`ll come to ours," he said.
