House Minority Leader Nancy Pelosi (D-California) demanded Tuesday that the Republican leadership strip Rep. Steve King (R-Iowa) of a committee chairmanship over a controversial tweet about immigration.

In the same remarks, she also referred to a top aide to President Donald Trump as a "white supremacist."

On Monday, King praised right-wing Dutch prime minister candidate Geert Wilders for statements he made regarding the lack of cultural assimilation in immigration to western Europe.

"Wilders understands that culture and demographics are our destiny. We can't restore our civilization with somebody else's babies," King tweeted.

In a statement, Pelosi called the comments "disgusting and racist" and demanded that Speaker Paul Ryan (R-Wisconsin) take away King's gavel as chairman of the House Judiciary Committee's Subcommittee on the Constitution and Civil Justice.

"The tepid, brush-off response from the Speaker and the GOP leadership is disgraceful," Pelosi said.

She then referred to White House Chief Strategist Steve Bannon as a "white supremacist," saying his prominence in the Trump administration "blinded Republicans to the difference between right and wrong."

Last night, King defended his remarks in an interview on "Tucker Carlson Tonight." Watch it HERE.
