District attorney's spokeswoman Farrah Emami says Wahler could face up to six months in jail and a $1,000 fine if convicted.

Emami says Wahler had a blood alcohol level of .19 percent when he was stopped by Newport Beach police on March 19 after officers saw him make an abrupt turn and stop in a traffic lane.
