Chief strategist Steve Bannon’s position in the White House appears as precarious as it’s ever been following a weekend of violence in Charlottesville, Virginia, and a stewing showdown with national security adviser H.R. McMaster.

Democrats and liberal activists are intensifying calls for Bannon’s ouster as they attempt to tie him to a weekend gathering of white nationalists and ensuing car crash that caused the death of one counterprotester and injuries to around 20 other people. They contend that Bannon, the former executive chairman of Breitbart News, is an enabler of the so-called alt-right movement that’s been associated with white nationalism, white supremacy and anti-Semitism.

His continued presence as a top Trump adviser amid the raised voice of racists means “it is now the White Supremacists’ House,” charged Rep. Maxine Waters, D-Calif. Democratic House Minority Leader Nancy Pelosi of California reiterated her previous call for the firing of Bannon, dubbing him an “alt-right white supremacist sympathizer.”
