CNN's Jim Acosta explains how Trump’s rallies evokes violent mob — calling it a ’cause and effect’ syndrome

During his Thursday night Montana rally, President Donald Trump praised Republican Rep. Greg Gianforte for assaulting a reporter— even while we are in the midst of unanswered question about missing Washington Post journalist Jamal Khashoggi.

While talking to CNN's Don Lemon, Jim Acosta explained how Trump's rallies only evoke fear. He detailed that he saw a Trump supporter doing wrestling moves in the crowd while Trump continued his attack on reporters.

"Not just once but twice tonight the president is making jokes about assaulting reporters while the whole world is demanding answers about the murder of a journalist who died in the most gruesome and vicious way possible," Acosta said.

Adding, "When the president made that joke about Greg Gianforte assaulting Ben Jacobs, I looked over to the crowd [and saw] one Trump supporter doing pro-wrestling moves, doing body slam type gestures in the crowd. So, the crowd was obviously eating this stuff up."

"People wonder whether or not there's a cause and effect —whether or not the president's rhetoric plants seeds of violence in his own supporters. I think it's pretty evident," he said.
