Sen. Chris Dodd (D-Conn.) is a "lying weasel," his most likely Republican opponent, former Rep. Rob Simmons, said late Thursday.

Simmons said the characterization of Dodd as a "lying weasel" echoed by conservative TV host Sean Hannity was correct.

"It's harsh, but I think it's correct. He asked by CNN whether he had anything to do with an amendment that protected the bonuses of those executives, and he said, 'Absolutely not,'" Simmons said. "Within a day, he recanted and came back and said that he had."

Simmons stopped short of calling Dodd "corrupt," though, only asserting Dodd had become comfortable in Washington.

"I think he's gotten very accustomed to the good life down in Washington, D.C.," Simmons said. "He's lost touch with his constituents up here in Connecticut."
