Denver (AP) Colorado House Speaker Andrew Romanoff says Assistant Majority Leader and Democratic State Representative Michael Garcia of Aurora has resigned.
Garcia is expected to release a statement later.
The Denver Post and the political web site Facethestate.com have reported that a female lobbyist accused Garcia of lewd behavior in a bar.
Neither the post nor the web site identified the woman.
House Speaker Andrew Romanoff announced the resignation and said it was effective immediately.
Parker Republican and House Minority Leader Mike May called Garcia's resignation “a sad ending for a great legislative career.”
But May said the resignation was proper if the allegations are true.
Garcia was first elected to the House in 2000 and planned to run for the State Senate this year. Term limits prevent him from running for the House again.
Romanoff announced the resignation, and clerks later read a brief statement from garcia “i hereby submit my resignation from the Colorado House of Representatives.”
Officials quickly removed his nameplate from his desk, and put black tape over his name on the voting board.
