AUSTIN (KXAN) — Texas Attorney General Ken Paxton responded to allegations against him Monday, saying an outside prosecutor will look over the investigation, and he will not be resigning.

Top aides to Paxton are accusing him of abuse of office, bribery and other criminal offenses, according to a letter obtained by the Austin American Statesman.

The letter, dated Oct. 1, is addressed to the attorney general’s director of human resources and says Paxton’s unlawful behavior, also including prohibitions relating to improper influence, was reported to law enforcement.

“The Texas Attorney General’s Office was referred a case from Travis County regarding allegations of crimes relating to the FBI, other government agencies and individuals,” Paxton wrote. “My obligation as attorney general is to conduct an investigation upon such referral. Because employees from my office impeded the investigation, and because I knew Nate Paul, I ultimately decided to hire an outside independent prosecutor to make his own independent determination. Despite the effort by rogue employees and their false allegations, I will continue to seek justice in Texas and will not be resigning.”

Earlier on Saturday, the Office of the Attorney General sent a statement in response to the allegations, saying, “The complaint filed against Attorney General Paxton was done to impede an ongoing investigation into criminal wrongdoing by public officials including employees of this office. Making false claims is a very serious matter and we plan to investigate this to the fullest extent of the law.”

Gov. Greg Abbott said in a statement to KXAN Sunday the “allegations raise serious concerns,” but that he wouldn’t comment further until the results of any investigation were complete.

Paxton is still under indictment for separate, previous charges of felony securities fraud from 2015. There is still no trail date set for that.

The Statesman report indicates First Assistant Jeffrey Mateer, and Deputy First Assistant Ryan Bangert were among the seven people who signed the complaint.

KXAN reached out to the FBI, but a spokeswoman declined to comment due to their policy. The Travis County District Attorney’s office said they “do not have an investigation.”
