Maryland state elections officials have cleared the campaigns of both Gov. Larry Hogan (R) and former lieutenant governor Anthony G. Brown (D) of separate allegations of misconduct during last year’s election.

The Maryland Democratic Party filed a complaint alleging that Hogan’s campaign was not paying the fair-market rate for use of a rock-star-sized campaign bus. Hogan personally bought the bus, and his campaign was paying him $683.77 a month for its use, the equivalent of Hogan’s monthly payment.

The Democratic Party contended the amount was unreasonably low.

Hogan’s campaign, meanwhile, accused Brown’s campaign of inappropriately coordinating with an independent committee that was largely funded by pro-Brown labor unions. The committee, “One State, One Future,” ran television ads during the gubernatorial primary critical of one of Brown’s Democratic opponents, then-Attorney General Douglas F. Gansler.

The Hogan complaint noted that Brown’s ticket used some of the same fundraising consultants as the independent committee, which Brown’s campaign said was not evidence of coordination.

In both cases, staff at the Maryland State Board of Elections determined there were no violations of law, and there are no plans to refer the episodes to the state prosecutor, said Jared DeMarinis, director of the division of candidacy and campaign finance.
