Apparently the Texas GOP does have a line

It's very low, but it's there. And Ken Paxton has crossed it. 

Maybe it's not the depth of the line, but the number of times you cross it. Anyway...

In an unanimous decision, a Republican-led House investigative committee that spent months quietly looking into [Texas AG Ken] Paxton recommended impeaching the state’s top lawyer on 20 articles, including bribery, unfitness for office and abuse of public trust.

You remember Ken Paxton.

Paxton has been under FBI investigation for years over accusations that he used his office to help a donor and was separately indicted on securities fraud charges in 2015, but has yet to stand trial.

[...]

The move sets up what could be a remarkably sudden downfall for one of the GOP’s most prominent legal combatants, who in 2020 asked the U.S. Supreme Court to overturn Joe Biden’s victory. Only two officials in Texas’ nearly 200-year history have been impeached [Gov. James Ferguson in 1917 and state Judge O.P. Carrillo in 1975].

[...]

Paxton suggested it was a political attack by the House’s “liberal” Republican speaker, Dade Phelan. He called for Phelan’s resignation and accused him of being drunk during a marathon session last Friday.

[...]

“The RINOs in the Texas Legislature are now on the same side as Joe Biden.”

Yes, Republicans are famously "liberal".

Impeachment requires a majority vote of the state’s usually 150-member House chamber, which Republicans now control 85-64, since a GOP representative resigned ahead of an expected vote to expel him over the finding that he had inappropriate sexual conduct with an intern.

It’s unclear how many supporters Paxton may have in the House. Since the prospect of impeachment suddenly emerged Wednesday, none of Texas other top Republicans have voiced support for Paxton.

The articles of impeachment issued by the investigative committee, which include three Republicans and two Democrats, stem largely from Paxton’s relationship with one of his wealthy donors. They 20 counts deal heavily with Paxton’s alleged efforts to protect the donor from a FBI investigation and his own attempts to thwart whistleblower complaints brought by his own staff.

[...]

Unlike in Congress, impeachment in Texas requires immediate removal from office until a trial is held in the Senate. Republican Gov. Greg Abbott could appoint an interim replacement. Final removal would require two-thirds support in the Senate, where Paxton’s wife’s, Angela, is a member.

[...]

In 2014, he admitted to violating Texas securities law over not registering as an investment advisor while soliciting clients. A year later, Paxton was indicted on felony securities charges by a grand jury in his hometown near Dallas, where he was accused of defrauding investors in a tech startup. He has pleaded not guilty to two felony counts that carry a potential sentence of five to 99 years in prison.

[...]

Paxton’s aides accused him of corruption and were all fired or quit after reporting him to the FBI. Four sued under Texas’ whistleblower laws, accusing Paxton of wrongful retaliation, and in February agreed to settle the case for $3.3 million. But the Texas House must approve the payout.

This is the state ATTORNEY GENERAL. Any wonder justice is what it is in Texas? 

 ...but hey, do what you want...you will anyway.

UPDATE 08:51 am:

UPDATE 05/28/2023:  Impeached.  121-23 vote.  Paxton has to step down until his case is adjudicated.  Governor Abbott will appoint someone to take his place in the interim.  Trump, Cruz, and other crooks are indignant.
