A New York attorney caught hurling a racist rant in a video posted Wednesday may now be facing disciplinary troubles, as a backlash has produced calls for his disbarment, prompted a U.S. Congressman to file a formal grievance and caused members of the public to write scathing reviews of his legal practice on social media.

According to news reports, Manhattan-based lawyer Aaron Schlossberg—whose law firm website touts his language fluency in Spanish—is the man seen in a video that quickly went viral. In the video, a white man who appears to be Schlossberg can be heard berating the manager at Fresh Kitchen after overhearing a conversation in Spanish between other employees. The man accuses them of all being “undocumented” and threatens to call U.S. Immigration and Customs Enforcement. “I pay for their welfare, I pay for their ability to be here. The least they can do is speak English,” he said.
