The anti-Semite charged with fatally shooting three people outside of Jewish community centers in Kansas last Sunday ranted to a Manhattan rabbi days before he opened fire about “getting rid of every Jew.”

Frazier Glenn Cross, 73, called the hot line for a charity that provides security to Jews in the conflict-torn areas of Ukraine and was connected to Rabbi Menachem Siegal, director of the United Jewish Communities of Eastern Europe and Asia.

Cross, a former Ku Klux Klan leader, blasted Siegal for raising money for Jews because they “cause all of the problems” and “destroyed the whole economy in the United States and the world.”

“He started going on a rampage and said Hitler should have finished off the job in Europe by coming to the United States and getting rid of every Jew,” Siegal told The Post of their March 30 conversation.

“I was like shocked, he sounded like an old man. I started talking to him and he said he was from Springfield, Missouri.”

Cross ranted that there were too many Jews in the Midwest, adding, “We have to get rid of them.”

“He kept calling me, ‘You Jews.’ He said, ‘You Jews are the ones that destroyed the whole economy in the United States and the world’ and he said, ‘You guys control all of the money.’ ”

“Then he said ‘you have the audacity to even raise money, you guys cause all of the problems and you’re going to suck more money out of the country.’ ”

Siegal provided a copy of the call log and caller ID for the conversation that lasted 10 minutes.

Cross referenced Hitler five times in the conversation, but did not hint to the rabbi that he planned to go on a killing spree.

The Department of Justice is investigating the phone call as part of its probe.

Cross allegedly killed three people, including a 14-year-old boy, during two shootings in Overland Park. All three victims were Christian.
