Trudeau under fire regarding G-G pick

Justin Trudeau claims that background checks are done on candidates before any high-profile appointment, but isn’t saying whether he knew about a charge against Julie Payette.  The new Governor General was up on second-degree assault back in 2011, but it was dismissed and expunged two weeks later.  The selection process to replace David Johnston was behind closed doors, so people wonder if the prime minister knew about this before.
