Cannon admits he is upset by the content of the posts, but insists he will not be "bullied" by his harsh critics.

He writes, "I was just showing y'all the type of stuff I deal with every morning. Got to make sure I got my armor on ... I never start stuff with anyone. I like making people smile. But y'all know the enemy is busy ... but I will not be bullied ... Some of the stuff is too disrespectful to retweet. But don't trip, y'all I can handle it, I'm a soldier I actually enjoy being the underdog..."
