National Democrats are launching a social media ad blitz in Arizona to call out Republican U.S. Rep. Eli Crane for flip-flopping on his promise to release more information on Jeffrey Epstein. The ad buy comes just days after congressional Democrats published a lewd birthday card from President Donald Trump to the convicted sex offender. “Donald Trump is hiding something, and Republicans in Congress are covering for him,” he said in a written statement. Trump campaigned for president by pledging to release federal case files into Epstein, but has since declared that it is “a hoax” as he’s resisted the transparency he promised. Trump and Epstein socialized frequently in high-profile circles, attending parties in Palm Beach and New York.
