In a lengthy Instagram post on Wednesday, the White Stripes rocker — who was called "a washed up, has-been loser" by White House Communications Director Steven Cheung on Tuesday — blasted Trump and his Administration, calling them "petty and pathetic and thin skinned."

"He's masquerading as a Christian, as a leader, as a person with actual empathy," he claimed. "He's been masquerading as a businessman for decades as nothing he's involved in has prospered except by using other people's money to find loophole after loophole and grift after grift.
