Sen. Bernie Sanders, I-Vt., called for the removal of President Trump's adviser Steve Bannon from the National Security Council.

In comments posted on Twitter, Sanders said Bannon is dangerous and must be ousted from the NSC.

Steve Bannon sitting on the National Security Council is dangerous and unprecedented. He must be removed. — Bernie Sanders (@SenSanders) January 30, 2017



We need experienced people who will protect our country on the National Security Council, not an extreme right-wing political operative. — Bernie Sanders (@SenSanders) January 30, 2017

Trump signed a memo on Saturday restructuring the NSC to include Bannon, the chief strategist in the White House.

Former National Security Adviser Susan Rice called the move "stone cold crazy," according to The Hill.

But White House spokesman Sean Spicer defended the move saying Bannon was previously an officer in the Navy.

The New York Times noted Bannon's "stated preference for blowing things up — as opposed to putting them back together — may not translate to his new role."
