Washington (CNN) President Donald Trump's chief economic adviser hosted white nationalist Peter Brimelow at his home last weekend, The Washington Post reported Tuesday.

Brimelow, who is known for espousing anti-immigrant ideals and for his role in the white nationalist website VDare, attended Larry Kudlow's birthday party in Connecticut, Kudlow told The Post.

Kudlow said he'd known Brimelow "forever" but that "we would never have invited him" had he known about Brimelow's white nationalist ties, according to the paper.

Kudlow also told The Post that Brimelow's immigration beliefs are "a side of Peter that I don't know." "I totally, utterly disagree with that point of view and have my whole life. I'm a civil rights Republican," he said, according to The Post.

The Post noted that Kudlow's party took place a day after reports surfaced that Trump speechwriter Darren Beattie had left the White House following questions surrounding his attendance of a conference frequented by white nationalists.
