Rep. Mark Foley, R-Fla., submitted a letter of resignation from Congress on Friday in the wake of questions about e-mails he wrote a former male page, according to a congressional official.
Foley, 52, had been considered a shoo-in for re-election until the e-mails surfaced in recent days.
Campaign aides had previously acknowledged that the Republican congressman e-mailed the former Capitol page five times, but had said there was nothing inappropriate about the exchange. The page was 16 at the time of the e-mail correspondence.
Foley's election opponent, Democrat Tim Mahoney, has called for an investigation.
