‘Murder’ shrink for gold bar Bob

To help in his corruptiontrial defense, embattled Democratic New Jersey Sen. Bob Menendez has hired a psychiatrist who testified for a double child murderer, The Post has learned.

Menendez, charged with 18 counts of corruption and bribery, paid Karen Rosenbaum, a forensic psychiatrist, $4,200 last month as an “expert witness,” newly released filings from his legal defense fund show.

The filing is the first hint at how Menendez will defend himself when he goes on trial in Manhattan federal court beginning May 6, charged with selling his office to foreign governments and receiving gold bars and cash in return.

Rosenbaum was an expert witness in the defense of Yoselyn Ortega, the nanny who went on trial in Manhattan in 2018 for the 2012 slaying of her two young charges, ages 6 and 2.

The psychiatrist testified Ortega could not be held accountable because she was in a state of psychosis, believing that Satan had ordered her to kill the kids.

Ortega was convicted and sentenced to life in prison without parole.

The newly unsealed motion also revealed Menendez may argue that his wife “withheld information” and led him to believe nothing illegal was occurring when the couple allegedly accepted cash and gold bars in exchange for political favors.

In the motion, Menendez asks the US District Court for the Southern District of New York to sever his case from his co-defendants, including wife Nadine, because if he takes the stand, he may testify about “marital communications” that could implicate her.

Menendez’s lawyers argue that the senator’s explanations “and the marital communications” will “exonerate” the three-term senator “by demonstrating the absence of any improper intent on Senator Menendez’s part.”
