Former Vice President Joe Biden will receive some help for his presidential campaign from a top figure in the Russia investigation. Andrew Weissmann, the former lead prosecutor on Robert Mueller’s special counsel team and a former U.S. Justice Department official, is scheduled to headline a virtual fundraiser for Biden, the presumptive Democratic nominee, on June 2, according to an invitation of the event obtained by The Wall Street Journal. The fundraiser is being billed as a “fireside chat” put on by the “Biden Victory Fund,” a joint fundraising committee between Biden’s presidential campaign and the Democratic National Committee. Weissmann reportedly left the Justice Department in April to join a private firm. Former U.N. ambassadors Samantha Power and Susan Rice will attend a virtual reception on the same day.
