Dodd acknowledged his role in the change after a Treasury Department official told CNN the administration pushed for the language.

Both Dodd and the official, who asked not to be named, said it was because administration officials were afraid the government would face numerous lawsuits without the new language.

Dodd, a Democrat, told CNN's Dana Bash and Wolf Blitzer that Obama administration officials pushed for the language to an amendment designed to limit bonuses and "golden parachutes" at those companies.

"The administration had expressed reservations," Dodd said. "They asked for modifications. The alternative was losing the amendment entirely."

On Tuesday, Dodd denied to CNN that he had anything to do with adding the language, which has been used by officials at bailed-out insurance giant AIG to justify paying millions of dollars in bonuses to executives after receiving federal money.
