Washington (CNN) - "Irresponsible," "reckless," and "destructive."
Those are the words used to describe tea party Republicans in a new TV commercial by Organizing for America, the non-profit political organization formed from President Barack Obama's re-election campaign that supports the president's agenda.
"The government shutdown is hurting veterans, seniors, and our kids. Now tea party Republicans are threatening an economic shutdown, refusing to pay our nation's bills, endangering American jobs," says the narrator in the spot, which OFA says will run on national cable television this week.
While the partial government shutdown and impending debt ceiling deadline have been the focus of some campaign- or lawmaker-specific ads the past two weeks, this appears to be the first national commercial dedicated to the shutdown, which is now a week old, and the debt ceiling, which faces a major deadline in 10 days.
The ad points to what it considers a lack of leadership by House Republican leaders, ending with the narrator saying, "Tell them to stand up to the tea party," over a photograph of House Speaker John Boehner, House Majority Leader Eric Cantor, and House Majority Whip Kevin McCarthy.
National polling conducted just before and just after the start of the shutdown indicates that slightly more Americans blame congressional Republicans than the White House and Democrats in Congress for the partial closure of the federal government.
OFA, a non-profit organization, morphed at the beginning of the year from Obama's 2012 re-election campaign, and is led by some key players from the campaign team. The group went up with spots over the summer in support of the new health care law, which was the signature domestic achievement of Obama's first term, and which remains in the crosshairs of Republicans hoping to defund, delay, or dismantle it.
The spot was first reported by NBC News.
