Mr. Obama, who took the unusual step of denouncing the court’s decision during this year’s State of the Union address, has made the case a staple of his current stump speech and criticized it twice during his Saturday morning radio and Internet addresses.

Mr. Obama’s chief political adviser, David Axelrod, continued that line of criticism Sunday, complaining that Republicans had blocked legislation to require groups that air political ads to reveal their donors.

“You know, there’s an old saying that if you want to keep things secret, you have something to hide,” Mr. Axelrod said on ABC’s “This Week.”
