ST. LOUIS (AP) — Republican state Rep. Paul Curtman will run for Missouri auditor in 2018.

Curtman announced his intention Tuesday in suburban St. Louis. He had earlier considered a run for U.S. Senate before ruling it out after Republican Attorney General Josh Hawley officially announced his candidacy for Democratic incumbent U.S. Sen. Claire McCaskill's seat.

Curtman, of Union, is the second Republican to formally announce a bid to unseat Democrat Nicole Galloway as auditor, along with St. Louis attorney and former University of Missouri curator David Wasinger.

Curtman is a former Marine first elected to the House in 2010.

Missouri Democratic Party chairman Stephen Webber said in a statement that Galloway's "independence and dedication to looking out for Missouri taxpayers is unmatched in Republican-controlled Jefferson City."
