The US presidential hopeful has had a star on the Hollywood Walk of Fame since 2007 following the success of reality television show The Apprentice.

However the gold and brass star has recently been subjected to vandalism, including a spray-painted swastika and pet poo, as many Americans take issue with the real estate mogul's rhetoric and policy plans, The Los Angeles Times reported.

However, officials of the Walk of Fame told The Times they have no plans to remove the star.

"The Hollywood Walk of Fame is a registered historic landmark," president of the Hollywood Chamber of Commerce, which operates the Walk of Fame," said Leron Gubler.

"Once a star has been added to the walk, it is considered a part of the historic fabric of the Hollywood Walk of Fame.
