Disgraced New Jersey Sen. Bob Menendez will resign from the Senate on Aug. 20 in the wake of his bribery conviction last week, a source familiar with the matter confirmed to The Post on Tuesday.

A deluge of Democrats had publicly demanded that the 70-year-old Dem pol step aside as he battled bribery allegations — and those calls only grew louder after a jury found him guilty on 16 counts for using his political perch to benefit Egypt, Qatar and three of his wealthy pals in exchange for hordes of cash, gold bars and other gifts.

Even after his conviction, Menendez continued to profess his innocence and vowed that he would forge ahead with an appeal. The three-term Democrat is facing up to decades in jail, with sentencing slated for Oct. 29.

Rumors quickly swirled that Menendez would bow out of the Senate, where he is out of allies. Even Senate Majority Leader Chuck Schumer (D-NY) publicly urged him to resign after his conviction.

That’s despite the Democrats’ slim 51-49 majority in the upper chamber. New Jersey Gov. Phil Murphy (D) would be tasked with appointing a replacement.

Initially, the scandal-scarred senator slapped down talk of him resigning.

“I can tell you that I have not resigned nor have I spoken to any so called allies,” Menendez told CBS News on Wednesday. “Seems to me that there is an effort to try to force me into a statement. Anyone who knows me knows that’s the worst way to achieve a goal with me.”

Earlier this month, he said he secured the necessary signatures needed to mount an independent bid for the Senate.

Menendez announced in March that he would not pursue re-election as a Democrat amid the bribery case against him.

Rep. Andy Kim (D-NJ) has since clinched the party’s nomination for the seat this cycle. He is the overwhelming favor to win that seat that has long been held by Democrats.

Polls had pegged Menendez as terminally underwater if he attempted to defend his seat come Nov. 5.

Still, the senator’s son, Rep. Rob Menendez (D-NJ), managed to survive a competitive primary last month, despite baggage from his father.

The elder Menendez had been a top voice on foreign policy in the upper chamber, but he was pressured into stepping down from the powerful Senate Committee on Foreign Relations last year due to the indictment.

Specifically, Menendez was found guilty of utilizing his political power to win gifts such as cash, 1-kilogram gold bars, a Mercedes-Benz convertible, and more in exchange for favors.

He denied those allegations.

Co-defendants in the case included his wife Nadine, 57, businessman Wael Hana, 40, and businessman Fred Daibes, 66, to give her. Both men were also convicted of padding Menendez’s pockets in exchange for benefits.

Nadine had been set to go on trial separately amid her treatment for breast cancer, but that start date has been delayed indefinitely.

Evidence compiled by prosecutors included photos of 13 gold bars — totaling roughly $150,000 in value — that were discovered inside his bedroom, wads of cash worth $14,500, envelopes of cash in his official Senate jacket, a trove of text messages, and more.

Prosecutors alleged that Menendez helped pen a letter asking the federal government to unfreeze $300 million worth of aid to Egypt that had been stalled due to human rights concerns, worked to protect Hana’s halal meat business, and more.

They outlined a slew of actions Menendez took between 2018 and 2022.
