During the Iran hostage crisis, did U.S. Sen. Bernie Sanders express support for the Iranian regime of Ayatollah Ruhollah Khomeini.?

Snopes  "In January 2020, we received multiple inquiries from readers about the accuracy of a social media meme that made striking claims about the past record of U.S. Sen. and 2020 Democratic presidential contender Bernie Sanders. The meme featured black-and-white photographs of Ayatollah Ruhollah Khomeini, who led the Islamic revolution of 1979 and became Iran’s supreme leader; former U.S. President Jimmy Carter; and Sanders, along with the following text: (In the illustration below.)

. . . "The claims contained in the meme appeared to borrow from two articles published in January 2020, just two weeks before the Democratic presidential primaries began in earnest with the Iowa caucuses. 

"On Jan. 16, The Daily Beast published an opinion column written by historian Ronald Radosh, which carried the headline, “When Iran Took Americans Hostage, Bernie Backed Iran’s Defenders.” There, Radosh wrote that Sanders “aligned himself with the Socialist Workers Party (SWP), the self-proclaimed Trotskyist revolutionary party, became its presidential elector in Vermont, and campaigned for its candidates and platform that defended the Iranian hostage seizure.”
"On Jan. 18, The Jerusalem Post published an article that bore the headline, “Bernie Sanders Backed a Party That Supported Iran During Hostage Crisis.” The piece largely restated portions of Radosh’s earlier column.

"Important differences exist between the claims made in the above-displayed meme, which contained several key falsehoods, and Radosh’s article, but the latter also omitted important context and made misleading assertions." . . .
