Texas Republican congressman Tony Gonzales is ending his bid for re-election but said he will serve out his term, following his admitting, after repeated denials, that he had an affair with a former staff member who later died by suicide.

Gonzales announced his plan late on Thursday after facing calls from party leadership to withdraw from the race for re-election this November. Others in Congress had called on him to resign his seat.
