The high court struck down the District of Columbia's 32-year-old ban on handgun possession, ruling that Americans have a constitutional right to keep guns in their homes for self-defense.

When asked about his reaction, Obama disputed the one outlined earlier by his campaign, ABC News reported.

When a reporter noted in November that the District's handgun law was constitutional, Obama distanced himself from the campaign, the network reported.

"I don't know what my aide said but I've been very consistent, I teach constitutional law," Obama said. "What I said was that I believe Second Amendment as being an individual right and have said that consistently. I also think that individual right is constrained by the rights of the community to maintain issues with public safety. I don't think those two principles are contradictory and in fact what I've been saying consistently is what the Supreme Court essentially said today."

Obama, the junior senator from Illinois, said although the District's gun ban was overturned, the court did affirm the right of local communities to engage in background checks and other "common sense laws."
