President Donald Trump doubled down Wednesday on Somali immigrants living in the U.S., saying, "they've destroyed our country."

"Somalians should be out of here. They’ve destroyed our country," Trump said to reporters in the Oval Office.

The president’s comments on Wednesday followed Minneapolis Mayor Jacob Frey saying Trump repeatedly slamming Somali immigrants “violates the moral fabric of what we stand by in this country as Americans.”

Trump responded that Frey was a “fool” and proceeded to slam Somalia for the second day in a row.

“It’s not even a nation,” Trump said of Somalia, saying it was “just people walking around killing each other.”

The president also suggested that Somalia may be the worst country on Earth and that, though he’d never visited, he hoped never to do so.

The Minneapolis-St. Paul area is home to about 84,000 people of Somali descent, nearly one-third of the Somalis living in the U.S.

Refugees from the East African nation have been coming to the frigid plains of Minnesota since the 1990s, drawn by the state’s generous social services and an ever-growing diaspora community.

They have become increasingly prominent in the state, serving on the Minneapolis and St. Paul city councils and in the state legislature. Democratic Rep. Ilhan Omar – a regular target of Trump, who on Tuesday singled her out specifically as “garbage” - represents part of the state in the U.S. House.

The president’s comment came days after his administration announced it is halting all asylum decisions following the shooting of two National Guard soldiers in Washington. The suspect is originally from Afghanistan but Trump has used the moment to raise questions about immigrants from other nations, including Somalia.

He also spoke soon after a person familiar with the planning said federal authorities are preparing a targeted immigration enforcement operation in Minnesota that would primarily focus on Somali immigrants living unlawfully in the U.S.
