A lobbying group has cut ties with an ex-adviser to former President Barack Obama after videos surfaced that show the man making Islamophobic comments and threats to a food cart employee in New York City.

The videos, posted on X (formerly Twitter) by a Columbia University student, shows Stuart Seldowitz asking someone off camera, “Did you rape your daughter like Muhammad did?” and saying that killing 4,000 Palestinian children “wasn’t enough.”

Seldowitz was acting director for the National Security Council South Asia Directorate under Obama and was deputy director/senior political officer in the U.S. State Department’s Office of Israel and Palestinian Affairs from 1999 to 2003. More recently, he served as foreign affairs chair for Gotham Government Relations, which announced his new role in a press release in November 2022.

On Tuesday afternoon, Gotham announced on Twitter that it had cut ties with Seldowitz.
