Hillary Clinton may be against Donald Trump's proposal to build a wall along America's southern border, but a temporary wall will be constructed around the venue hosting next month's Democratic National Convention — where Clinton is expected to earn the presidential nomination.The wall, according to NBC Philadelphia, will be raised for security reasons. The station reports the fencing will enclose the Wells Fargo Center, in which the convention will take place, along with the nearby Xfinity Live! venue. Pope Francis visited Philadelphia last fall, a visit that shut down many parts of the city and had citizens staring at walls that had been erected. The convention, slated for July 25-28, will not take up as large a footprint."This is not the papal visit. This is much smaller in scope and much smaller in scale. So the security footprint is going to be much smaller," Secret Service Special Agent James Henry told NBC. "The impacts are really minimal. We're fortunate the sports complex is more isolated, certainly than the papal visit in Center City."A protest zone will be set up in FDR Park, which is close to the Wells Fargo Center but will be outside of the security walls."The perimeter will not be any bigger than it needs to be," Henry said.Several thousand "Occupy DNC" protesters all who support Vermont Sen. Bernie Sanders for president over Clinton, are expected to be at the event. They are booking spots at campgrounds around 20 minutes away in southern New Jersey.
