 U.S. Senator John Hoeven says he believes the Secret Service should have to answer to security lapses that allowed someone being able to have a gun on a roof nearby and to be able to take a shot at former President Donald Trump. Clearly there was a breakdown in the security. We need to understand exactly what happened. There's no way this individual should have been on a rooftop that close with a clear line of sight and able to shoot at President Trump. There's no way.
