NEW YORK – Michael Avenatti, the combative lawyer who gained fame by representing porn star Stormy Daniels in lawsuits involving President Donald Trump, was convicted Friday of trying to extort sportswear giant Nike. The verdict was returned by a federal jury in Manhattan after a three-week trial in which prosecutors said Avenatti threatened to use his media access to hurt Nike’s reputation and stock price unless the company paid him up to $25 million. The convictions for attempted extortion and honest services fraud carry a combined potential penalty of 42 years in prison. Avenatti glared at the jurors as the verdict was being announced but said nothing. Afterward, he shook hands with his lawyers and told them “great job” before he was led back to the cell where he has been held since a judge found he had violated his bail conditions. His lawyer, Scott Srebnick, said he would appeal the conviction.
