I have it on good second-hand authority that the friend of an uncle of a professor of a college where my aunt’s child went heard it on the radio that the mother of a man who read it on the internet heard that some guy was talking about, on the subway, that he heard his barber met a prostitute who saw a police report about a poster about this girl who saw on TV that three guys in a bar were talking about a politician who mentioned in a press conference that he heard his father had mentioned that he saw read some magazine that said that Kevin Bacon had overheard from a news anchor that four girls in an elementary school mentioned that their parents had heard on their CB radio that a trucker had saw some guy who said that he had a friend who knew a roomate of his who had a girlfriend that overheard at a Phish concert that someone called Schumer a big Jew.
Apparently that was the same fact check source that enabled the media to believe Schumer’s claim as true.
. . . seems solid to me . . .
