House GOP set to vote on revamped debt-limit bill

WASHINGTON (AP) - House Republicans are pressing ahead with a vote on a newly modified plan to stave off an unprecedented government default next week, even though the legislation faces a White House veto threat and unanimous opposition among Senate Democrats. The vote set for today comes amid growing worry that a dysfunctional Congress might remain gridlocked and plunge the nation into default. Nervous investors sent the Dow Jones industrial average down almost 200 points Wednesday, on top of a 92-point drop the day before.
