Rep. Teresa Leger Fernandez, N.M., introduced an expulsion resolution against Rep. Tony Gonzales, R-Texas, on Tuesday after the embattled lawmaker failed to meet her deadline to resign from Congress. 

Gonzales announced his plans on Monday to “file his retirement” but did not specify when he planned to step aside.

The Texas Republican’s plans to resign come after he admitted to an extramarital affair with a former staffer earlier this year after repeatedly denying the allegations.

Teresa Leger Fernandez vowed to introduce an expulsion resolution targeting Gonzales if he did not resign by Tuesday at 2 p.m. Eastern time.
