Sirhan Sirhan, the Palestinian refugee found guilty of shooting US Senator and presidential candidate Robert F. Kennedy to death in 1968, was “hypnotized” by Jewish criminal organizations to kill RFK, an American scholar and political commentator says.

Sirhan, 75, was hospitalized Friday after being stabbed by a fellow inmate at a prison in San Diego, California.

A statement from the California Department of Corrections and Rehabilitation said the stabbing occurred Friday afternoon at the Richard J. Donovan Correctional Facility near San Diego.

“Sirhan Sirhan was hypnotized to randomly fire many shots and indeed the number of shots fired in that incident greatly exceeded the number of bullets in Sirhan Sirhan’s gun,” said Kevin Barrett, an author, journalist and radio host in Madison, Wisconsin.

“These gangsters that we call Kosher Nostra, or ethnically Jewish organized crime with a fanatical loyalty to Israel, very likely has been behind the worst crimes in modern American history,” Barrett told Press TV during a phone interview Saturday.

The Kosher Nostra was responsible for “killing President [John F.] Kennedy to stop him from shutting down Israel’s nuclear weapons program, killing his brother to prevent justice from emerging from RFK and killing JFK Jr. of course in the late 1990s to prevent him from becoming president and reopening these cases,” Barrett added.

Sirhan has been imprisoned for more than 50 years for the murder of RFK,, a US senator from the state of New York and Democratic presidential candidate.

Sirhan was convicted of shooting Kennedy on June 5, 1968, immediately after he had declared victory in the previous day's California Democratic presidential primary.

An autopsy report shows Kennedy was shot in the back, while Sirhan was standing in front of him. Reports through the years also indicated 13 shots were fired that day when Sirhan’s gun only held eight bullets. Several witnesses said Sirhan wasn't close to the senator.

Kennedy, 42, was later buried at Arlington Cemetery, near his brother, former President John F. Kennedy, who was assassinated in 1963.

RFK’s third oldest child, Robert F. Kennedy Jr., revealed in 2018 that he doesn’t believe Sirhan had carried out the assassination and believes a second shooter was involved.

Paul Schrade, who was shot in the head while walking behind Kennedy, has also claimed that Sirhan didn’t shoot the politician.

Schrade, 93, believes Sirhan’s bullets struck him and four others wounded that day, but he didn’t shoot Kennedy.
