Trump suggests he would have picked another AG who could have blocked Russia probe

In his latest public slam at Attorney General Jeff Sessions -- who, citing his involvement with the Trump campaign, recused himself from the investigation last year, paving the way for the appointment of special counsel Robert Mueller -- Trump said he would have "quickly picked someone else" had he known about the recusal.

"The Russian Witch Hunt Hoax continues, all because Jeff Sessions didn't tell me he was going to recuse himself," Trump tweeted Tuesday. "I would have quickly picked someone else. So much time and money wasted, so many lives ruined...and Sessions knew better than most that there was No Collusion!"

Trump on Monday called the Mueller investigation "unconstitutional" and said he had the power the pardon himself, but added that he had no plans to do so. His attorneys in recent days have argued that, as President, Trump has broad immunity from prosecution and can't be indicted for a crime, including obstruction of justice. But the Supreme Court has never squarely ruled on the question, and many legal experts disagree.
