Hillary Clinton's trusted aide first left Weiner back in August 2016. They separated after he was caught in his second sexting scandal. As she put it then, "After long and painful consideration and work on my marriage, I have made the decision to separate from my husband."

That separation came in the middle of campaign season. The FBI's investigation into emails on Weiner's computer was announced days before voters went to the polls, and possibly impacted the result.
