Michael Avenatti, the disgraced attorney who once represented adult film star Stormy Daniels, said he has been in contact with Donald Trump’s legal team about testifying in the former president’s New York trial, according to a report from the New York Post.

Avenatti is serving a 19-year sentence at a low-security prison in Los Angeles for various extortion, fraud, and embezzlement convictions, including identity theft and wire fraud for stealing from Daniels. He told the outlet from prison that he would be “more than happy to testify” in the Trump trial and that he had been in touch with the presumptive Republican presidential nominee’s legal team “for the better part of a year.”
