Texas Attorney General Ken Paxton is gearing up for a potential U.S. Senate run while no longer shadowed by a federal corruption investigation that hung over his rising profile in the Republican Party. Paxton, a close ally of President Donald Trump, has hinted at challenging Cornyn for more than a year but has not said when he will make a decision. In the final weeks of the Biden administration, the Justice Department decided not to pursue its investigation into Paxton over bribery allegations, according to two people familiar with the matter who spoke to The Associated Press on the condition of anonymity to discuss internal deliberations.
