Senator Chuck Schumer forgot to check his dirty mouth for a flight on Sunday.
The New York senator was overheard calling a female flight attendant a "bitch" after she insisted that he shut off his cellphone so the plane could take off.
A Republican aide who witnessed the incident claims Schumer muttered the insult to none other than Senator Kirsten Gillibrand.
According to Politico, who first reported the story, the aide quotes Schumer as saying, "It's Harry Reid calling. I guess health care will have to wait until we land."
Schumer's spokesman later apologized for the incident, say that the senator "made an off-the-cuff comment under his breath that he shouldn't have made, and he regrets it."
