The daughter of late New York Senator Daniel Patrick Moynihan (D-N.Y.) was caught spewing racist hate on camera on Sunday.

A clip of the incident has been making the rounds online. It quickly rose to the top of Reddit’s r/PublicFreakout, collecting nearly 4,000 upvotes in less than a day.

The clip begins after the initial altercation has passed. According to the man who posted the video, 31-year-old Dan Lee, he and a friend were told to “go back to China” by an unknown woman. He then followed the woman, who has since been identified as Maura Moynihan, to her cab, where he confronted her over her racist outburst.
