Although a man was arrested for a number of gun charges, the Secret Service, federal agencies, and local law enforcement all did their job in making sure the suspect was nowhere near Trump at the time of the rally. While investigations are ongoing, at least there's no evidence this was a further assassination attempt. Republicans have been reckless in their rhetoric to blame Democrats for these incidents and they must not leverage these moments for political points.
This man whipped the media into a frenzy, making it appear to be a third assassination attempt. It turns out Miller was just another avid Trump supporter and he just so happened to be carrying firearms in his truck as he always did. It's the left-leaning media ecosystem that needs to tamp down the rhetoric — Miller has declared his innocence and Trump's campaign has asserted that the former president was never in danger.
