"This foolish guy Josh Earnest, I don't know if he's talking to President Obama," Trump said at a stop in Hershey, Pennsylvania, on what his aides have billed as a "Thank You Tour."
"He is so bad, the way he delivers a message," the President-elect continued. "He can deliver a positive message and it sounds bad. He could say, 'Ladies and gentlemen, today we have totally defeated ISIS,' and it wouldn't sound good."
He then suggested that Earnest is "getting his orders from somebody else" other than President Barack Obama.
"Does that make sense?" Trump asked the crowd. "Could that be possible?"
Earnest suggested at his daily press briefing Thursday afternoon that Trump "obviously knew that Russia was engaged in malicious cyber activity that was helping him" and called on the President-elect's transition team to support an investigation into the attacks.
