Donald Trump's campaign manager says that a Trump protester involved in a disturbance at a rally in Reno, was "a Democratic plant or operative." Trump was speaking to supporters when chaos broke out in the crowd, and Secret Service agents pulled Trump off stage. A man claiming to be the protester said he was carrying a sign that read "Republicans against Trump" when he was attacked. The man said he heard one person yell "something about a gun." Kellyanne Conway tells CNN's "State of the Union" that the protester was canvassing for Clinton and was put there by the Democratic campaign, but offered no details or proof.
