President Obama will join forces with former president Bill Clinton later this month for a fundraising event at the McLean home of former Democratic National Committee chairman Terry McAuliffe, according to an Obama campaign official.

The April 29 event will mark the first joint Obama-Clinton fundraiser of the 2012 election cycle. News of the fundraiser was first reported Monday evening by National Journal.

McAuliffe, a longtime Clinton family confidant, served as chairman of Hillary Rodham Clinton’s 2008 presidential bid. He pursued an unsuccessful bid for Virginia governor in 2009 and is widely expected to run again next year.

In an interview that aired on MSNBC earlier Monday, Bill Clinton said he is planning to join Obama for three joint fundraisers this year and expects to hit the campaign trail on the president’s behalf.

News of the fundraisers comes as the Obama campaign is kicking off its reelection efforts in earnest. On Monday night, the campaign unveiled a new TV ad, its second of the cycle. Like the first spot, the latest one is energy-themed.

It also takes aim -- by name -- at the GOP front-runner, Mitt Romney, arguing that the former Massachusetts governor is beholden to Big Oil.
