Obama, clapper, Brennan, all of them hated Flynn because he was a man of honor and would not bend to their corrupt ways.

He refused to lie to Congress about how the war in Iraq was going and that was one of the final nails in the coffin for him.

Him having access to all the intel made him a serious liability to criminals...hence the reason they tried to get rid of him and then slapped a gag order on him.
