Donald Trump: The Border Wall Is Already Up

As soon as Donald Trump's Presidential run became official, the wall went up ... around his star on the Hollywood Walk of Fame.

Someone with a great sense of humor erected a 6-inch high concrete wall Tuesday -- complete with tiny barbed wire -- around the Donald's star. Most people are crediting popular street artist Plastic Jesus for the wall ... since he's done several other anti-Trump pieces -- like "No Trump Anytime" signs.
