Supreme Court Chief Justice John Roberts recently weighed in on controversial comments President Barack Obama made during his first the State of The Union Address.

The president criticized a Supreme Court decision that will allow corporations and unions to spend money on political ads.

In a lecture given on Tuesday to University of Alabama law students Roberts, the Republican nominee who joined the court in 2005, said it's "very troubling" to hear remarks about the court in that setting."

Roberts said he wonders if justices should even attend the annual State of the Union speech that he says "has degenerated into a political pep rally."
