July 24, 2012, 9:30 amPortland police will be working OVERTIME today as the President makes a fundraising stop in town. Chris Brown tells us which areas you'll want to AVOID: MLK will be SHUT DOWN from Multnomah to the I-84 ramps until the President leaves. You'll also want to plan around a closure of the Convention Center max stop. Sergeant Pete Simpson says the REAL fun could come this afternoon or evening when the president heads BACK to the Air National Guard base and Airforce One. Stick with KXL for updates all day long ... we'll stay on top of the closures and traffic delays.
