I sure didn't. Don't recall ever hearing about a gaggle. After this episode I started reading lots of article's and that is when I understood the difference.
The lying LSM are acting like this is an unforgivable sin, Obummer did it all the time, only met with those favorable to him.
A normal press briefing includes ALL these despicable reporter jerks, wish they could be shut out, that would PLEASE me.
A Gaggle was something Hillary usually did on her air plane. She would walk back to the reporters section on the plane and talk to them. It was a question time but it was prestty much softball questions and apparently they were given drinks while travelling on her plane. The gaggle was more a photo opt time and someone would post a stream on twitter in order to show Hillary as a sweet fun loving person to follow. Not kidding.
