Cell phone footage surfaced Monday showing a man yelling, “Kill Muslims,” purportedly at a group of Muslims in Grand Rapids, Michigan, before walking off, chanting, “Trump! Trump! Trump!” The video comes as Republican front-runner Donald Trump’s campaign has been under scrutiny in recent weeks for accusations that it is fostering rally violence and anti-immigrant and anti-Muslim sentiment.

The video was recorded in downtown Grand Rapids near Rosa Parks Circle Sunday, MLive reported Tuesday. Candy Valenzuela, a passerby, shared the video on her Facebook feed. It was viewed more than 45,000 times as of Tuesday morning. The video includes explicit language.

"Kill them all! Kill them all!" the man is heard yelling. "Kill you all. Kill the Muslims."

Valenzuela wrote on social media: “This just happened right in front of my eyes. A group of Muslims preaching knowledge and this guy walks by and just starts yelling Trump! If you cant hear it clearly, at the end he starts yelling Trump! After the video he actually walked by them, tried to swing, missed and fell! __ #racismstillexist.”

Critics of Trump’s campaign have held him accountable for allegedly egging on violence at his rallies. Earlier this month, a pro-Trump rallygoer was charged for sucker-punching a protester.

The real estate mogul has also been criticized for using inflammatory, simplistic language about Muslims. Earlier this month, Trump said "Islam hates us," and late last year he proposed a complete temporary ban on all Muslims' entering the U.S.

A poll found that about 84 percent of Trump’s supporters back the idea of banning Muslims. On Saturday, Trump supporter William Celli was sentenced to 90 days behind bars and ordered to attend anger management classes after posting a picture of a homemade bomb on social media and threatening to kill Muslims.

The Council on American-Islamic Relations, a civil rights organization, has repeatedly demanded the Republican presidential candidate apologize for his purportedly anti-Muslim statements and stances. Trump has generally responded by doubling down, sometimes taking his controversial views a step further. While many thought support for his campaign would ultimately wane due to his inflammatory rhetoric, the billionaire remains the clear front-runner for the Republican nomination.
