Officials at the Secret Service are reportedly encouraging Trump campaign planners to book indoor arenas and other enclosed sites for future political rallies, not outdoor venues, the Washington Post reports, apparently expressing concerns that no outdoor site can be completely secure from gunfire or other attacks.
Trump’s campaign officials appear to be heeding the warning, with planners scouting municipal centers and basketball arenas for future events. Of course, that would give Secret Service ways to limit access to the line of sight to the stage, but it also gives media a better gauge of the size of the crowd, rather than custom-built outdoor sites where Trump event organizers can wrangle a small number of people to look like a lot to cameras.
