U.S. Attorney Jesse Laslovich told MTN, "Mr. Branson conspired with others on the scheme for which he is charged over the course of six years from approximately January 2015 through March of 2021. But we know he was doing it longer dating back to the late eighties. He thought this was funny, but he's not laughing today."Another man, Simon Paul, has been accused of trafficking the federally-protected birds with Branson but he has not been convicted.
