Texas Republican Rep. Tony Gonzales has faced increasing pressure from his party to resign or drop out of his race after allegations of an affair with a staffer.

Texas Republican Representative Tony Gonzales faces a primary runoff to stand for reelection in the November midterms after weeks of instability around his position, following allegations of misconduct with a former staffer.

The Texas 23rd Congressional District race is projected to head to a runoff, as incumbent Rep. Tony Gonzales, who was accused of having an affair with a staffer who later died by suicide, and conservative activist Brandon Herrera both failed to receive more than 50% of the vote.

Rep. Tony Gonzales (R-Texas) and Brandon Herrera are heading to a runoff election for the Republican nomination for Texas' 23rd District. Why it matters: Gonzales has been embattled by allegations that he had an affair with his former staffer before she died by suicide.

I made a mistake,” said the Texas Republican, hours after the House Ethics Committee announced it would investigate allegations that he “engaged in sexual misconduct.”
