Tuesday on MSNBC’s “Morning Joe,” Tom Brokaw, the former anchor of NBC’s “Nightly News,” discussed the role anger has played in the 2016 election cycle on both sides of the political spectrum.

Brokaw traced it all the way back the Sept. 11, 2001 terrorist attacks, through the Iraq war and into the Obama presidency.

But also during that segment, Brokaw discussed Breitbart News and how Breitbart is playing a role in this presidential cycle.

“Now what happens is the mechanisms feed a lot of this anger,” Brokaw said. “So I’m in touch with my friends at Breitbart a lot. They got their own system going all 24/7. They’re very smart. They know where their folks are and they’ve played it with what they see and find unacceptable 24/7. So a lot of the instrumentation is designed to keep people stirred up.”
