Rep. Tony Gonzales, a Texas Republican, announced he is stepping down from Congress after admitting to an extramarital affair with a staffer.
The decision comes amid a House Ethics Committee investigation into allegations of sexual misconduct and workplace discrimination.
Tony Gonzales said he takes responsibility for his actions and previously ended his re-election campaign but had planned to finish his term.
The controversy also involves allegations tied to a former staffer who later died by suicide, which he has denied contributing to, The Guardian has reported.
His resignation follows growing bipartisan pressure and calls for his expulsion from Congress.
