Jack White needled Donald Trump after it was announced that the president would be slapping his signature on U.S. banknotes.

The White Stripes frontman described Trump as a “manipulative, loophole finding, egomaniacal, conman” in a lengthy Instagram post on Friday.

“Oh how humble!” White wrote. “But why stop there donnie? Why don’t you use your small hands to sign into law that your oh so stern orange face appears on the front of the hundred dollar bill as well?”

For more than a century, currency has featured the names of the U.S. Treasury Secretary and the Treasurer. However, Trump will soon become the first sitting U.S. president to have his autograph on America’s money. According to The New York Times, Trump’s signature will appear alongside that of Treasury Secretary Scott Bessent. The name of the U.S. treasurer will be removed.

White didn’t let Trump’s enablers off the hook, either.
