Trump's tweet 'is an incitement to violence': Ana Navarro

Ana Navarro responded to Trump's tweet Sunday morning.

“I am disappointed beyond belief by the answer that the homeland security adviser just gave," Navarro said. "What a wuss. What a wuss. You could see that he is ceding his principles. You are the homeland security adviser and you can’t stand here and say the difference between right and wrong."

Bossert touted the president’s use of social media as a way to reach people by bypassing conventional media outlets.

Bossert, who saw the tweet for the first time live on "This Week," told Raddatz, “There’s a lot of cable new shows that reach directly into hundreds of thousands of viewers and they’re really not all very fair to the president. So I’m pretty proud of the president for developing a Twitter and a social media platform where he can talk directly to the American people.”
