Just days after Texas Attorney General Ken Paxton accused the state House speaker of presiding over the chamber while drunk and called on him to resign, a GOP-led House ethics panel heard explosive testimony from investigators detailing what they described as years of misconduct by the attorney general, later recommending his impeachment.

The week鈥檚 events marked an eruption of simmering tensions between two of the top Republicans in the most populous red state.

The remarkable outburst of public acrimony has been years in the making. Paxton, a more conservative figure who aligned himself with former President Donald Trump and used his office to challenge the 2020 presidential election results, has long cast House leadership as too liberal.

His attacks on state House Speaker Dade Phelan are a vivid window into a political environment where Republicans control all levers of state government but are split into multiple factions battling for power and influence.

Paxton on Tuesday posted on Twitter a letter to the state House General Investigating Committee, the chamber鈥檚 ethics panel, asking for an investigation into Phelan for performing his duties in what Paxton described as 鈥渁n obviously intoxicated state.鈥

Paxton鈥檚 call for Phelan鈥檚 resignation came after video circulated on social media over the weekend of Phelan appearing to slur his words as he presided over the House chamber at the end of Friday鈥檚 late-night session.

Paxton did not present any evidence beyond the video clips to support his claim that Phelan was drunk.

鈥淚t is with profound disappointment that I call on Speaker Dade Phelan to resign at the end of this legislative session,鈥 Paxton said in a statement posted to his Twitter account. 鈥淭exans were dismayed to witness his performance presiding over the Texas House in a state of apparent debilitating intoxication.鈥

Less than an hour later, the state House General Investigating Committee 鈥 a panel that investigates corruption in state government and has the power to initiate impeachment proceedings 鈥 revealed it had subpoenaed records from Paxton鈥檚 office as part of an investigation Phelan鈥檚 office said started in March.

The five-person committee voted unanimously Thursday to recommend Paxton鈥檚 impeachment, filing 20 articles with the state House. It was not immediately clear when the full chamber would consider it.

鈥淛ust yesterday, four liberals put forward a report to the House General Investigating Committee based on hearsay and gossip, parroting long-disproven claims. Today, that Committee has asked the Texas House of Representatives to use their unsubstantiated report to overturn the results of a free and fair election,鈥 Paxton said in part in a Thursday statement.

鈥淭his process provided no opportunity for rebuttal or due process. They even refused to allow a senior attorney from my office to provide the facts. They rejected every attempt to seek a full accounting of the truth,鈥 he continued.

Phelan鈥檚 office said Paxton鈥檚 allegation was merely retaliation for the House ethics panel鈥檚 probe.

鈥淢r. Paxton鈥檚 statement today amounts to little more than a last ditch effort to save face,鈥 Phelan communications director Cait Wittman said in a statement Tuesday.

Democratic state Rep. Terry Canales said that the broader context of Friday鈥檚 all-day session made clear that Phelan 鈥渨as not under the influence.鈥

鈥淎t that point in the night the House had been in session over 13 hours and we had been doing so for multiple days in a row. We were all exhausted,鈥 Canales said in a statement. 鈥淣evertheless, I had multiple interactions with the speaker throughout the day and that night and I can say unequivocally he was not under the influence.鈥

The acrimony between Phelan and Paxton underscores the personal and ideological tensions within the GOP as the party approaches its 2024 presidential primary.

Phelan has also clashed in recent months with another more conservative Republican official, Lt. Gov. Dan Patrick, over property tax relief, school choice and other key issues.

The state House hearing is the latest in a string of legal troubles for Paxton. CNN has previously reported that he was facing an FBI investigation for abuse of office and that Justice Department prosecutors in Washington, DC, took over the corruption investigation. He is also under indictment for securities fraud in a separate, unrelated case. Paxton has denied all charges and allegations.

On Wednesday, a team of lawyers working with the House ethics panel spent three hours laying out details of allegations of misconduct against Paxton spanning years.

The probe began in March after Paxton sought to use US$3.3 million in state dollars to settle a whistleblower lawsuit after four former employees of the attorney general鈥檚 office accused him of using his authority to benefit political friend Nate Paul, a real estate investor who had donated tens of thousands of dollars to Paxton鈥檚 campaign. In the settlement, Paxton apologized but did not admit fault or accept liability. He denied wrongdoing and said in a statement he had agreed to the settlement 鈥渢o put this issue to rest.鈥

As the hearing took place on Wednesday, the Texas Tribune reported that Paxton called into Dallas radio host Mark Davis鈥 show and criticized the investigation.
