RACHEL CAMPOS-DUFFY (FOX NEWS CONTRIBUTOR): [President Donald Trump] kind of joked about it. There were a couple times where he said, you know, I usually say “you're a liberal socialist,” and today I'm going to say [different tone] “you're a liberal socialist.” So today he kind of joked about how he had to keep his tone down, that he was on his best behavior. Definitely he was keeping it under control in light of what was happening. 

...

A lot of the the people I spoke to in the crowd by the way, Ainsley, Brian, and Steve, they said, listen, conservatives are the ones who really know what it feels like to have that kind of hate thrown at them whether it's on college campuses. People also in the crowd complained to me that outside of a rally like this, they felt unsafe wearing their Trump gear. So, that tells you a little bit about the political environment out there.
