Trump's security upgraded after attack, agents wall him off from RNC crowds

On the floor of the Republican National Convention Tuesday evening, vice presidential candidate JD Vance greeted and shook hands with excited delegates as he walked toward his seat.

It was a marked contrast from former President Donald Trump, who entered the hall a few minutes later and was separated from supporters by a column of Secret Service agents. His ear still bandaged after an attempted assassination, Trump closely hugged the wall. Instead of handshakes or hellos for those gathered, he offered fist pumps to the cameras.

The contrast underscores the new reality facing Trump after a gunman opened fire at his rally in Pennsylvania Saturday, raising serious questions about the agency that is tasked with protecting the president, former presidents and major-party candidates. Trump's campaign must also adjust to a new reality after he came millimeters from death or serious injury - and as law enforcement warns of the potential for more political violence.
