CHARLESTON, S.C. — The driving under the influence case against a South Carolina state senator can go to trial, but the jury won’t hear results of the lawmaker’s breath-test that found he was over the legal limit to drive, a judge has ruled.

After registering 0.09 percent on the breath test shortly after a wreck Nov. 4, state Sen. Paul Campbell requested a blood test that was not administered, his lawyer said.

Under state law, a DUI suspect must be helped to a blood test if they request one, magistrate Elbert Duffie ruled this week.

Troopers charged Campbell after the vehicle he in rear-ended a car in traffic on Interstate 26 in Charleston on Nov. 4. Campbell told officers his wife was driving, but the women driving the other car said Campbell and his wife switched places after the wreck. Both Campbell and his wife are also charged with giving false information to police.

Campbell’s lawyer had asked for the DUI charge to be thrown out because the dashboard camera video of his sobriety test did not show his feet. But Duffie ruled the video showed enough of the walk and turn portion of the test to be admissible at a trial.

Troopers have released the video of the arrest of the Goose Creek Republican on the side of the interstate and his booking at jail. It includes the breath test where Campbell’s blood-alcohol level registered 0.09 percent.

Campbell questioned the test’s accuracy and asks for a blood test.

“This is all we got,” the trooper responded on the video.
