Los Angeles provocateur Plastic Jesus just rained on Donald Trump's parade. On a day when the real estate mogul is celebrating his official coronation as the Republican Party's presidential nominee for 2016, Plastic Jesus has built a wall around Trump's star on the Hollywood Walk of Fame.

The wall only measures 6 inches high, but its statement is mighty.

Trump has vowed to build a wall along the United States' border with Mexico in order to keep out unauthorized immigrants. His stance, along with a pledge to halt Muslim immigration, has brought wide criticism from pro-immigrant groups.

The piece is described by a representative of the British-born street artist as a “gray concrete wall … complete with 'keep out' signs and topped with razor wire.”

Plastic Jesus is behind other headline-generating pieces, including a life-size Oscar statue that appears to be shooting up heroin.

His latest motto, “Stop making stupid people famous,” is featured on the miniature wall.
