The removal of Steve Bannon from the White House caps off President Trump's worst week in office, according to Bret Baier.

On "Happening Now," Baier said that Bannon, who served as Trump's chief strategist, was long expected to be the next member of the administration to go.

"This was something that had been brewing for some time," he said. "But it facilitated itself this week."

He pointed out that Trump's chief of staff, deputy chief of staff, press secretary, national security adviser and communications director have all resigned or been removed from their positions in just the first six months of his administration.

Bannon's last day in the White House comes at the end of a week in which Trump took heavy criticism for his response to last weekend's Charlottesville violence, in which a counter-protester was killed at a white nationalist rally.

Baier said this is "clearly the worst week" of Trump's presidency, and he needs to get back to working with Republican lawmakers to implement his agenda.

"You have some big things that are going to happen in the next two weeks - the raising of the debt ceiling, the budget," he explained. "These things deal with the shutting down of government potentially. And he'll need Capitol Hill to get on its horse."
