WASHINGTON – With gun legislation taking shape on Capitol Hill, President Barack Obama has kept a low profile on an issue he has made a critical part of his second-term agenda.

The president has not been highly visible in the debate during the past three weeks as gun bills are being written. He’s been embroiled in a budget battle that has dominated his time and for now is letting Vice President Joe Biden bang the drum for tighter firearms laws.

White House officials say the president plans to speak out on gun control as the issue moves toward a Senate vote in the coming weeks. But for now, he’s staying out of delicate negotiations among lawmakers. The White House says he will become more vocal if the legislative process hits a roadblock.
