The Fourth Circuit has determined that a conviction for attempted robbery under the Hobbs Act is not categorically a crime of violence under the federal sentencing law. “The Government may obtain a conviction for attempted Hobbs Act robbery by proving that: (1) the defendant specifically intended to commit robbery by means of a threat to use physical force; and (2) the defendant took a substantial step corroborating that intent. The substantial step need not be violent.”
