Richard Nixon made negative comments about Jews, blacks and other ethnic groups during informal discussions with top aides and his personal secretary that were recorded before he resigned as president, according to newly released tapes.

“I’ve just recognized that, you know, all people have certain traits,” said Nixon during a Feb. 13, 1973, conversation with Charles Colson that was included among 265 hours of tapes released by the Nixon Presidential Library and Museum.

“The Jews have certain traits. The Irish have certain — for example, the Irish can’t drink. What you always have to remember with the Irish is they get mean. Virtually every Irish I’ve known gets mean when he drinks. It’s sort of a natural trait. Particularly the real Irish,” Nixon said.

“The Italians, of course, just don’t have their heads screwed on tight. They are wonderful people, but …” he trailed off, adding later: “The Jews are just a very aggressive and abrasive and obnoxious personality.”

During another conversation with his personal secretary, Rose Mary Woods, Nixon expresses doubt about the opinion of William Rogers, his secretary of state, about black Africans.

“Bill Rogers has got somewhat — and to his credit it’s a decent feeling — but somewhat, sort of, a sort of blind spot on the black thing because he’s been in New York,” Nixon said.

“He says, well, ‘They are coming along, and that after all, they are going to strengthen our country in the end because they are strong physically and some of them are smart.’ So forth and so on.”

In another conversation with Woods, Nixon argued that Jewish people tend to be insecure.
