President Trump ratcheted up his attacks on Attorney General Jeff Sessions on Saturday, tweeting that Sessions was “scared stiff” and “Missing in Action” in defending him amid special counsel Robert Mueller’s probe into possible ties between the Trump campaign and Russia.

Trump slammed Christopher Steele, the former British intelligence officer at the center of the Trump dossier scandal, and the Department of Justice (DOJ) and once again slammed Mueller’s investigation as a “witch hunt.”

“The big story that the Fake News Media refuses to report is lowlife Christopher Steele’s many meetings with Deputy A.G. Bruce Ohr and his beautiful wife, Nelly. It was Fusion GPS that hired Steele to write the phony & discredited Dossier, paid for by Crooked Hillary & the DNC,” Trump tweeted.
