President Donald Trump dared former CIA director John Brennan to sue him over the revocation of his classified clearance.

The president ramped up his feud Monday morning with the former intelligence official after announcing last week that Brennan no longer had access to classified information.

"I hope John Brennan, the worst CIA Director in our country’s history, brings a lawsuit," Trump tweeted. "It will then be very easy to get all of his records, texts, emails and documents to show not only the poor job he did, but how he was involved with the Mueller Rigged Witch Hunt. He won’t sue!"

Brennan said the day before that he may pursue legal action against the president, who revoked his security clearance last month and announced the move last week.

Trump admitted he revoked Brennan's clearance as punishment for his criticism, and dozens of former top intelligence officials signed on to a letter blasting the move.
