ANNAPOLIS, Md. (AP) — The Maryland Democratic Party is asking the state board of elections to investigate possible campaign finance violations by Gov. Larry Hogan. The Democrats say the Republican took donations from 100 benefactors that were over the legal limit.

The Democrats’ executive director Ben Smith said Hogan’s 2018 campaign raked in more than $200,000 in violation of the legal limit of $6,000 per donor.

The Washington Post reports Maryland Sen. Clarence Lam noticed the possible violations after Hogan vetoed a bill to strengthen transparency in the governor’s appointments office.

Lam told the Democratic Party, which then found the other possible violations.

Hogan’s attorney denies the accusations, and says the campaign refunded at least five of the donations that exceeded the limit.
