Senator Bob Menendez of New Jersey has been found guilty in his federal corruption trial in New York.

The verdict was reached after about 13 hours of deliberations over three days.

Menendez was accused of “corruption on a massive scale,” with prosecutors alleging he accepted bribes in exchange for official acts.

As the verdict was read, Menendez, 70, occasionally glanced at the jury and appeared to mark a document in front of him. Afterward, he rested his chin on his closed hands, elbows on the table. He and his lawyers vowed to appeal as they left the courthouse.

“I have never been anything but a patriot of my country and for my country. I have never, ever been a foreign agent,” Menendez stated.

The jury’s verdict followed a nine-week trial where prosecutors argued that the Democrat abused his office’s power to protect allies from criminal investigations and enrich associates, including his wife, by performing acts such as meeting with Egyptian intelligence officials and facilitating millions of dollars in U.S. military aid to Egypt.

Menendez did not testify, maintaining publicly that he was only fulfilling his duties as the chairman of the Senate Foreign Relations Committee. He claimed the gold bars found in his New Jersey home by the FBI belonged to his wife, Nadine Menendez, who was also charged. Her trial was postponed due to her recovery from breast cancer surgery. She has pleaded not guilty.

The verdict, delivered at a federal courthouse in Manhattan, comes four months before Election Day and likely jeopardizes Menendez’s chances of campaigning for reelection as an independent candidate.

Menendez was convicted of all 16 counts he faced. His co-defendants, Wael Hanna and Fred Daibes, were also convicted of all counts they faced. The two New Jersey businessmen had pleaded not guilty. Another businessman pleaded guilty before the trial and testified against Menendez and the other defendants.
