Trump is boasting to friends and advisers that he expects Mueller to clear him of wrongdoing in the coming weeks, according to sources familiar with the conversations. The President seems so convinced of his impending exoneration that he is telling associates Mueller will soon write a letter clearing him that Trump can brandish to Washington and the world in a bid to finally emerge from the cloud of suspicion that has loomed over the first chapter of his presidency, the sources said.
Interesting theory.
