Rubin, 57, had been taken from his cell at the federal Metropolitan Detention Center in downtown Los Angeles at about 5 a.m. PST (8 a.m. EST) on Monday when he slashed his throat with a razor blade and then jumped or fell over a railing.
He was rushed to Los Angeles County-USC Medical Center and underwent surgery for wounds to his neck and throat and severe head injuries from the fall but did not regain consciousness, U.S. Marshal's spokesman William Woolsey said.
The fiery, controversial Rubin, who emigrated to the United States from Canada in 1961 and has been national chairman of the JDL since 1985, was arrested in December and charged along with another member, Earl Krugel, with the bomb plot on the testimony of an undercover informant.
Prosecutors say that Rubin and Krugel conspired with the informant to plant bombs at the King Fahd Mosque in the Los Angeles suburb of Culver City and an office of Rep. Darrell Issa, a California Republican of Lebanese Christian descent.
