David Trone has helped fund the campaigns of more than 50 elected officials who have since endorsed him in his Democratic U.S. Senate primary contest against Angela Alsobrooks, according to federal and state campaign records. Among those receiving contributions from the wealthy congressman in recent years are 31 current or former U.S. House members and dozens of state officials such as Attorney General Anthony Brown and Prince George’s County State’s Attorney Aisha Braveboy.
