On Tuesday, President Trump tweeted his anger at U.S. Attorney General Jeff Sessions, saying, in reference to the ongoing investigation by special counsel Robert Muller: “If we had a real Attorney General, this Witch Hunt would never have been started. Looking at the wrong people.”

This isn’t the first time that Trump has expressed his anger with Sessions, who recused himself from the investigation into the Russian interference in the 2016 election. Indeed, the president said previously that had he known that Sessions would recuse himself, he would have “put a different attorney general in.”
