“Congressman Ryan made clear at the time of the citation and ever since that he was not intoxicated, and we’re pleased that the court agreed and dismissed the case," Lowry said.
The arrest occurred Aug. 25. Ryan was released on his own recognizance and later pleaded not guilty.
Lowry said Ryan was in town for a staff wedding.
The Lexington, Va., Police Department said it could not provide any details on the circumstances of the arrest, citing state law.
The congressman himself was not at today's hearing because the House is in session, Lowry said.
Ryan, 39, a former star local high school quarterback, has been a member of Congress since 2003 and previously served in the Ohio state Senate.
He has reportedly been considering a run for governor in 2014, when Gov. John Kasich (R) will be up for a second term. He said in November that he would decide in the next few months whether to pursue higher office.
