I said that earlier.
And whether one wants to accept it or not, he’s a Frontrunner for The republican nominee for POTUS and SS doesn’t want ANYONE touching him.
Women can’t stab or shoot? yeah, the odds are out there but the SS takes no chances.
Aside from JFK, killed at long distance by multiple rifle shots, every actual or attempted presidential assassination involved the perpetrator getting dangerously close to his/her target. Thus,the SS must keep a safe distance between each of its protectees and persons, including members of the press, who are not specifically allowed to approach those protectees. IF the SS fails, then a member of the protectee’s staff needs to move FAST to prevent a possible atrocity.
