FORMER VICE PRESIDENT JOE BIDEN’S CAMPAIGN has canceled plans for a fundraiser headlined by Andrew Weissmann, a former top prosecutor with Robert Mueller’s special counsel team who has been a lightning rod among supporters of President Trump. The June 2 event had been billed as a “fireside chat” with Weissmann, who departed Mueller’s team last year and is working on a book about his role in the probe, and Anne Milgram, a former New Jersey attorney general. The fundraiser was pulled shortly after it was posted late last week, but not before it garnered widespread media attention, people familiar with the decision told the Journal’s Ken Thomas.
