An Indiana attorney has been arrested on drunken driving charges shortly after announcing his candidacy for the state Legislature.

Indiana State Police say Charles Richard Martin, who also goes by “Rick,” was arrested Thursday after midnight. The 50-year-old faces misdemeanor charges of operating a vehicle while intoxicated and was cited for speeding 65 mph in a 45 mph zone, among other things.

Martin has held several positions in the Republican Party. On Tuesday the attorney had announced his bid to succeed Republican Rep. Ron Bacon, who’s not seeking re-election.

Martin didn’t return a Sunday message seeking comment.
