Aug. 6 (UPI) -- Texas Attorney General Ken Paxton on Wednesday launched an investigation into potential Democratic presidential candidate Beto O'Rourke over allegations that he "bribed" Democratic state lawmakers who fled the Lone Star State to prevent Republicans from passing GOP-favorable congressional maps that critics say strip power from voters of color.

Paxton announced the investigation amid a deepening row between the state's Democrats and Republicans. The state's minority Democrats fled Texas over the weekend to deny Republicans the quorum needed to certify the controversial maps. The state's Republican leadership has responded with threats of arrest and to vacate their congressional seats if they don't return by Friday, as well as investigations into anyone who solicits funds to support their effort.

Paxton said Wednesday that he is investigating the O'Rourke-led Powered by People, which is reportedly covering the costs of Texas Democrats who fled the state.

He also said the Powered by People group may have violated bribery laws and state laws, such as those governing campaign or officeholder contributions and expenditures, coercion of a public servant and abuse of office.

"Any Democrat coward breaking the law by taking a Beto Bribe will be held accountable," Paxton said in a statement announcing the investigation. "These jet-setting runaways have already lost public trust by abandoning our state, and Texans deserve to know if they received illegal bribes to do it."
