The defense for President Obama's uncle is challenging the driving record of the police officer who arrested him on suspicion of drunken driving.

Onyango Obama, an illegal immigrant, briefly appeared in Framingham District Court on Thursday. His lawyer said he's investigating whether the officer has a pattern of poor driving.

Officer Val Krishtal arrested Obama, the half-brother of the president's late father, in Framingham in August. Krishtal said Obama made a rolling stop at a stop sign and nearly caused his cruiser to crash into Obama's sport utility vehicle.

Krishtal said Obama registered 0.14 on a blood-alcohol test, higher than the state's legal limit of 0.08.

Obama's lawyer also is seeking to suppress those results and evidence from the traffic stop.

Krishtal totaled his cruiser in November while responding to reports about gunshots.
