Minnesota Rep. Keith Ellison claimed Monday night that President Trump’s rhetoric is “green-lighting ugly and hate” and tied the president’s rhetoric and travel ban to a deadly attack by a Bernie Sanders supporter in Portland last month.

Ellison also claimed that two rallies in the nation’s capital last weekend, the “Freedom of Speech Rally” and the “Rally Against Political Violence” were “white supremacist rallies” inspired by Trump’s rhetoric. The latter rally was planned after some participants objected to the participation of white nationalist Richard Spencer in the “Freedom of Speech Rally.”

“This last weekend, there were two white supremacist rallies, one was at the White House, the other was at the Lincoln Memorial,” Ellison said on MSNBC’s “All In With Chris Hayes” while speaking about Trump’s travel ban, parts of which the Supreme Court allowed to take effect on Monday.

“I believe the rhetoric of the president is fueling some of the ugliest, most pernicious elements in our society. He is green-lighting ugly and hate and some of these folks are getting aggressive and we know about what happened in Portland a few weeks ago,” said Ellison, who also serves as the deputy chair of the Democratic National Committee. “My take is that there is more than simply this ban at stake. It is the culture and climate of our society.”
