TUSCALOOSA (AP) — U.S. Supreme Court Chief Justice John Roberts says the scene at this year’s State of the Union address by President Obama was “very troubling,” and he wonders if justices should even attend in the future.

With members of the court seated before him in the House chamber, Obama chided the court in January for its decision that corporations and unions could freely spend money to run political ads for or against specific candidates.

Roberts was on the University of Alabama campus to deliver the School of Law’s spring 2010 Albritton Lecture, by Andalusia native William Harold Albritton III, senior judge on the U.S. District Court for the Middle District of Alabama.
