Sen. Bob Menendez, D-N.J., abused his position as chairman of the Senate Foreign Relations Committee to “put greed first,” a federal prosecutor told jurors Wednesday during opening statements in the senator’s bribery trial.

Asst. U.S. Attorney Lara Pomerantz told the panel of 12 jurors and six alternates in New York that the senior senator from New Jersey “was powerful. He was also corrupt.”

“For years he betrayed the people he was supposed to serve by taking bribes,” she said.

Menendez is charged with accepting “hundreds of thousands of dollars” in bribes — including in the form of gold bars — in return for official acts as a U.S. senator.

“This was not politics as usual. This was politics for profit,” Pomerantz said.

Menendez has pleaded not guilty. He faces decades in prison if convicted.

His attorney, Avi Weitzman, told the jury during his opening statements that Pomerantz’s accusations were “outrageously false.”

“He did not violate the law,” Weitzman said. “There won’t be a single piece of tangible evidence the senator accepted a bribe,” he said. “There is an innocent explanation for the gold and the cash.”

Weitzman said the senator did not know that his wife had the gold bars, and that jurors shouldn’t judge someone by who they live with. Nadine Menendez has been charged in the scheme, but she will stand trial later because of a health issue.

Prosecutors said Menendez and his wife accepted bribes from three New Jersey businessmen in return for the senator’s help with various issues. Two of the businessmen — Fred Daibes and Wael Hana — have pleaded not guilty and are standing trial with Menendez. The third, Jose Uribe, pleaded guilty this year and agreed to cooperate with the probe.

Attorneys for Daibes and Hana will deliver their opening statements Thursday.

The 2023 indictment alleges it was Daibes who gave the gold bars to Menendez and his wife, and that after a dinner with Daibes, the senator searched on Google for “one kilo gold price.”

Prosecutors have said that Menendez made positive statements about Qatar to help Daibes get a multimillion-dollar investment from a company tied to the country and “provided sensitive U.S. Government information” and taken “other steps that secretly aided the Government of Egypt” in return for bribes from Hana.

The indictment alleges that when federal investigators searched Menendez’s home in New Jersey, they found over $480,000 in cash nestled away in the residence he shares with his wife, “much of it stuffed into envelopes and hidden in clothing, closets, and a safe.”

The indictment further alleges that the couple received “gold bars, payments toward a home mortgage, compensation for a low-or-no-show job, a luxury vehicle and other items of value,” such as jewelry and exercise equipment.

Menendez has denied any wrongdoing, and maintained the cash is all his. “For 30 years, I have withdrawn thousands of dollars in cash from my personal savings account, which I have kept for emergencies and because of the history of my family facing confiscation in Cuba,” he said in a statement in September.

The trial, which is taking place roughly two blocks from where former President Donald Trump is standing trial, is expected to last five to seven weeks.

Menendez stepped down as chair of the Foreign Relations Committee soon after he was indicted in September. He’s faced numerous calls to resign from members of his own party, including fellow New Jersey Sen. Cory Booker. Menendez announced in March that he would not run for re-election as a Democrat this year, but left the door open to a possible run as an independent if he’s exonerated.

The trial is the second time Menendez, who became a senator in 2006, has stood trial on federal charges. He was charged in 2015 with illegally accepting favors from a Florida eye doctor, including flights on a private jet, a stay at a five-star hotel in Paris, and more than $750,000 in political contributions for him and the Democratic Party. The case ended in a mistrial in 2017 after jurors were unable to reach a unanimous verdict. Prosecutors ultimately decided not to retry him.
