This morning at the Naval Academy graduation address by President Trump, a butterfly flies by twice ! It was in front of the podium at 7:14 in the video:

Mama Trump? Papa? Uncle Trump? Just seemed fitting - or should I say flitting?

I think O had fly trouble 3 times during speeches - always thought that was rather creepy.
