Trump doubled down on his comments Monday during an event at the White House, denying that he was being racist and expressing no remorse when told that white nationalist groups found common cause with his message.

“It doesn’t concern me because many people agree with me,” Trump told reporters on the South Lawn of the White House during an event designed to highlight American manufacturing.

Other Senate Republicans stopped short of calling Trump's remarks racist.

"Identify politics is a poison. It's toxic. ... The president shouldn't have written that. I think it damages him. It damages the country," he said.

When a reporter noted that if another individual made comments similar to Trump's they would be viewed as racist, Rubio added, "Most certainly I think people could take it that way, be offended by it."

"I … actually, honestly, haven't read anything except what you all have reported. But the reality is that I want to shift back onto the issues," Tillis said.

Pressed about whether he thought Trump's tweets were racist, Tillis added, "I literally don't go on Twitter."
