Republican Rep. Adam Kinzinger said Wednesday that if Republicans went forward with a plan supported by some conservatives to defund Obamacare in an upcoming vote they would lose the House of Representatives to Democrats in the 2014 midterm elections. Kinzinger was speaking at an Americans for Prosperity Illinois chapter meeting in Rochelle, Illinois.

"Potentially there will be a collapse of will to keep the government shut down because soldiers are not getting paid and all this other stuff's happening and we turn around and lose 10 to 20 seats in 2014," Kinzinger said. "And whether we win the battle or not, we've lost the war because Nancy Pelosi's now speaker of the House."

"This is not a disagreement on whether or not we hate the health care bill," the congressman continued. "This is a disagreement on tactics in terms of what is the best way to ensure that in the future we can repeal this law without bringing down the American economy or bringing down the Republican majority in the House."

Later, Kinzinger added: "I don't think the defunding thing is going to work, and I think we are going to lose the House in 2014, potentially."

In another video of the event posted on YouTube, the Illinois congressman called the Obama administration's response to the Sept. 11 terrorist attack in Benghazi, Libya, "inexcusable" and "un-American."
