Senator Schumer reportedly caused a scene at a restaurant in Manhattan, where he lost his cool with a female Trump supporter.

Page Six reports:

Schumer, the top Senate Democrat, lost his cool on Sunday night at Upper East Side restaurant Sette Mezzo, according to witnesses.

He was dining with friends when he encountered Joseph A. Califano Jr. — the former US secretary of health, education and welfare under President Jimmy Carter and domestic policy adviser to President Lyndon B. Johnson — and his wife, Hilary, who were having a quiet dinner.

Onlookers said Schumer was incensed that Hilary — the daughter of William S. Paley, the founder and chairman of CBS — had voted for Trump, even though her husband, Joseph, is a well-known Democrat.

As if making a scene in the restaurant wasn’t bad enough, onlookers said the angry Senator followed the group out of the restaurant and continued yelling.

One witness said of the restaurant rant, “They are a highly respected couple, and Schumer made a scene, yelling, ‘She voted for Trump!’ The Califanos left the restaurant, but Schumer followed them outside.” On the sidewalk, Schumer carried on with his fantastical filibuster: “ ‘How could you vote for Trump? He’s a liar!’ He kept repeating, ‘He’s a liar!’ ”

Hillary confirmed the confrontation:

“Sen. Schumer was really rude . . . He’s our senator, and I don’t really like him. Yes, I voted for Trump. Schumer joined us outside and he told me Trump was a liar. I should have told him that Hillary Clinton was a liar, but I was so surprised I didn’t say anything.”

Which of course Sen. Schumer’s office disputes:

A spokesman for Schumer said, “[He] and his wife ate at the café on Sunday, engaging in unremarkable conversation with patrons who approached their table. There were no heated exchanges with ‎anyone.”

If the reports are true, it wouldn’t be the first time Sen. Schumer has lost his temper in public. In 2009, Schumer reportedly called a flight attendant a “bitch” when she asked him to turn his phone off.
