Donald Trump-themed swastika graffiti was discovered in Philadelphia Wednesday morning following the US election victory for the billionaire real estate mogul.

Vandals spray-painted the word “Trump” on a window, with the letter “T” in Trump’s name replaced with the Nazi symbol.

They also daubed “Sieg Hiel” [in German, “hail victory,” a chant by supporters of the Third Reich] with a swastika.

Philadelphia Mayor Jim Kenney “condemned in the strongest possible terms” the graffiti, the Philly Voice news site reported.

“As I said in my statement to residents today, in the wake of the election, Philadelphians must work tirelessly to bridge the divides that have plagued this nation for decades,” Kenney said. “I know that many residents are planning to take part in vigils and rallies tonight and in the days ahead, and I urge you to gather respectfully and peacefully.”

The Philadelphia branch of the Anti-Defamation League also condemned the graffiti. Nancy Baron-Baer, the regional director of the ADL, said she “horrified” by the graffiti, the Philly Voice said.

Trump’s campaign has been dogged over the last several months with accusations that it drew the support of anti-Semites and other racists.
