Robert Mueller is finally bringing down the hammer, and Steve Bannon is nervous.

The former White House chief strategist is increasingly concerned that President Donald Trump’s legal team is falling down on the job. And he’s worried that they’ve left the president vulnerable as former campaign aides are being handed indictments.

“In terms of Steve’s thinking of how the president is handling this, yeah, he thinks the legal team was not prepared for what happened today—they’re not serving the president well,” a source close to Bannon said.
