Impeached Texas Attorney General Ken Paxton and now-indicted Austin real estate investor Nate Paul set up an Uber account under a fake name that Paxton used to see his mistress, revealing the extent of the men’s relationship as the FBI targeted Paul for possible mortgage fraud, a new filing in Paxton’s upcoming impeachment trial contends.

Paxton, who is suspended from office pending the outcome of his Sept. 5 Senate impeachment trial, used the account — under the name “Dave P,” which was jointly accessed by both men — to travel to the Pearl Lantana Apartments in Southwest Austin more than a dozen times between August and October 2020 to visit the woman, according to the filing from House impeachment lawyers.

All the while, the filing contends, Paxton and Paul met about 20 to 24 times in the spring and summer of 2020 — and one late night that fall — and discussed ways the state’s top lawyer could help Paul as the FBI stepped up its investigation into the real estate investor. A federal indictment alleges that Paul overstated his wealth and understated his liabilities in order to obtain up to $172 million in loans.
