"Everybody's kind of a little bit numb," Rep. Jack Kingston, R-Ga., was quoted as saying in Sunday's Washington Post. "There's this, 'What else can happen now?' feeling going around here."
The latest problems involve two Republican House members who resigned their committee assignments last week after the FBI raided their wives' businesses.
Reps. John T. Doolittle, of California, and Rick Renzi, of Arizona, said their wives will be exonerated, but the raids kept the focus on the ethical and legal clouds over GOP House members, the Post said.
Two other GOP House members face allegations that they pressured a U.S. attorney in New Mexico to indict Democrats and a third, Rep. Gary G. Miller, R-Calif., is being investigated by the FBI on whether he paid taxes on a land sale.
Rep. Tom Cole, R-Okla., predicted the scandals will not hurt his party's chances to regain control of Congress in 2008.
"There's a long time between now and the election," Cole said.
