The White House says congressional Republicans are using the investigation into a bankrupt solar energy company as a partisan "political football."
Spokesman Jay Carney says GOP lawmakers have "cherry-picked" certain documents trying to create controversy over a decision-making process that the White House insists involved no political influence.
Carney's comments follow a House committee's release of emails Wednesday showing that a major donor to President Barack Obama discussed the company, Solyndra, with White House officials.
The administration has contended that the donor, George Kaiser, never discussed the company with the White House.
Solyndra was the first renewable energy company to receive a federal loan under the 2009 stimulus law. The company declared bankruptcy in September, leaving taxpayers on the hook for more than a half-billion dollars.
