A lawyer allegedly hired by Texas Attorney General Ken Paxton to look into claims made by real estate developer Nate Paul said Tuesday that the Lone Star State’s top law enforcement officer misled him, and that a Paxton aide told him to “eat” an invoice for his work.

“You guys reached out to me to go and do a job, and then, now you’re pulling the rug out from under me, and I’m getting these cease-and-desist letters, and now my name is being thrown through the mud in the media, and this is a totally new world to me,” attorney Brandon Cammack recalled telling Paxton in testimony on the witness stand.

Paxton is accused of misusing his office to help Paul, his friend and campaign donor. Cammack said Tuesday that he was hired by Paxton and began investigating Paul’s claims, reporting directly to the attorney general and working without official credentials.

He also said Paxton asked to communicate via encrypted messaging services and called from two separate cell phones, prompting Cammack to get a second phone so as not to miss his calls.
