Former The White Stripes frontman Jack White scorned the Trump administration on Wednesday after the White House called him a "washed-up loser."In a lengthy Instagram post, White retaliated against White House communications director Steven Cheung calling him a "has-been" with an anti-Trump screed that questioned President Donald Trumps humanity, and called him a "conman," as well as a "low life fascist.""No intelligent person can defend this low life fascist. This bankrupter of casinos. This failed seller of trump steaks, trump vodka, trump water, etc.," he wrote.

It's now a vulgar, gold leafed and gaudy, professional wrestler's dressing room," the musician said."Can't wait for the UFC match on the front lawn too, he's almost fully achieved the movie Idiocracy," he added, mentioning Trumps ambitions to host a UFC fight in front of the White House next year as part of Americas 250th birthday celebrations.SMITHSONIAN TEMPORARILY REMOVES TRUMP IMPEACHMENT REFERENCES FROM HISTORY MUSEUM, DRAWING LIBERAL IREThough White started the feud with the administration, his response to Cheung accused the Trump team of being thin-skinned."How petty and pathetic and thin skinned could this administration get?

I'm not going to be like one of the silent minority of 1930's Germany. This man is a danger to not just America but the entire world and that's not an exaggeration, he's dismantling democracy and endangering the planet on a daily basis, and we. all. know. it." he said.Cheung responded to White's Instagram post, telling Fox News Digital, "Trump Deranged liberals like him are so predictable and easily triggered.
