House Republicans unveiled a new midterm messaging sign attacking Democrats over a false claim about transgender mice, prompting mockery from critics.

House Republicans, during a press conference, displayed a sign contrasting 'common sense' Republicans cutting taxes with 'crazy' Democrats accused of 'trans-ing the mice' — a misleading reference to President Donald Trump's false claim about taxpayer-funded transgenic mouse medical research — which drew mockery from Punchbowl News founder Jake Sherman, strategist Mike Nellis, and Everytown's Max Steele on social media.
