Leaders of four House minority caucus groups have written a letter calling upon President Donald Trump to boot White House staff aides Steve Bannon, Stephen Miller and Sebastian Gorka.

The heads of the black, Hispanic, Asian and progressive caucuses are calling in the letter for the firings of the Trump administration officials in the wake of a violent, racist rally in Charlottesville, Virginia. The letter asserts their continuing presence in the White House is emboldening a resurgent white supremacist movement in America.

"Americans deserve to know that white nationalists, white supremacists, and neo-Nazis are not in a position to influence U.S. policy," says the letter dated Monday. "In this time of tumult in our country, Americans deserve a leader that will bring us all together and denounce those who seek to tear us apart."

Meanwhile, protesters on Manhattan's Fifth Avenue tried to spoil Trump's homecoming Monday night with signs bearing messages like "stop the hate, stop the lies" and chanting "shame, shame, shame" and "not my president!"

After two days of public equivocation and internal White House debate, the president condemned white supremacist groups by name Monday, declaring "racism is evil".

In a hastily arranged statement at the White House, Trump branded members of the KKK, neo-Nazis and white supremacists who take part in violence as "criminals and thugs."
