The campaign to reelect President Barack Obama and senior White House officials are keeping quiet on whether he supports an effort to add gay marriage to the 2012 Democratic Party platform.

During an appearance Sunday on ABC's This Week, White House senior adviser David Plouffe declined to comment on the issue.

“We don't even have a platform committee,” Plouffe said. “We are going to work through the platform process.”

Earlier this month, Obama campaign manager Jim Messina gave reporters during a conference call a similar non-response.

“Look, we're a big tent party here,” Messina said. “POTUS has a great record on fighting for fundamental fairness for all Americans. You know, 'Don't Ask, Don't Tell,' and many other accomplishments we are very, very proud of. You know, there's a process – there's not even a delegate platform committee yet – there's a process to go through this discussion, and the DNC will go through that, and we will have a platform.”

The effort has won the endorsement of Los Angeles Mayor Antonio Villaraigosa, House Minority Leader Nancy Pelosi and 22 Democratic senators. Villaraigosa has also been named the chairman of the Democratic National Convention.
