There was a very real possibility that scandal-plagued Republican Rep. Tony Gonzales’ career was going to be derailed on Tuesday. That didn’t happen, at least it hasn’t yet: The incumbent congressman received roughly 42% of the vote in his primary, trailing far-right internet personality Brandon Herrera’s 43%, but since neither candidate topped 50% support, they both advanced to a May runoff.

But while Gonzales might’ve been relieved by the results, the day after the primary delivered a fresh round of devastating news. For one thing, one of his own GOP congressional colleagues filed a censure resolution against the Texan. For another, this soon followed by related news about the ethics probe he’s facing. CNBC reported:

The House Ethics Committee on Wednesday announced an investigation into Rep. Tony Gonzales, a Texas Republican who has come under fire for allegedly having a sexual relationship with a staffer who died by suicide last year.

The committee said it would investigate whether Gonzales ‘engaged in sexual misconduct towards an individual employed in his congressional office,’ or ‘discriminated unfairly by dispensing special favors or privileges.’

A Politico report, which has not been independently verified by MS NOW, added that the report prepared by the nonpartisan Office of Congressional Conduct included that congressional investigators found “a substantial reason to believe” that the Texas Republican did have a sexual relationship with his subordinate — an apparent violation of House rules.

The OCC findings are now in the hands of the House Ethics Committee, which often takes several months to complete an investigation and make recommendations about possible punishments.

Four House Republicans aren’t prepared to wait that long and have already called for Gonzales to resign based on the available information. (The GOP incumbent, a married father of six who’s long denied any wrongdoing, has spent a fair amount of time lately insisting that he will not quit.)

In theory, Donald Trump, who officially endorsed Gonzales, and House Speaker Mike Johnson of Louisiana could intervene and show the congressman the door, but in light of the Republicans’ vanishingly small majority in the chamber, MS NOW reported last week that many party officials see Gonzales as effectively “untouchable” because his party can’t afford to see him step down.

As for the underlying controversy, the scandal reached new heights two weeks ago, when The San Antonio Express-News, Gonzales’ hometown newspaper, reported on a text message from Regina Santos-Aviles, a former aide to the congressman, who said she had an extramarital affair with Gonzales. Santos-Aviles died by suicide last year.

While these allegations against the Texas Republican have come up before, the Express-News reported that a second former aide to the congressman came forward to say Santos-Aviles told him about the relationship. That same aide (who asked not to be named by the Express-News, citing a fear of retaliation) provided a text message from Santos-Aviles in which she said she “had an affair with our boss.” (He shared the same evidence with The New York Times.)

Last week, a lawyer for Santos-Aviles’ husband disclosed additional sexually explicit text messages that the GOP congressman allegedly sent to his former aide. While MS NOW has not independently verified the authenticity of the texts, they were reviewed in detail by the Times, the Express-News, The Wall Street Journal, NBC News, Politico and The Texas Tribune.

Gonzales, meanwhile, hasn’t said much about the allegations, though he recently accused his primary rival and Santos-Aviles’ husband of trying to blackmail him.

The primary runoff is in 12 weeks. Watch this space.
