(CNN) — Democratic Sen. Bob Menendez of New Jersey remained defiant on Monday after being indicted on bribery charges at the end of last week, saying he believes he will be exonerated as he responded to some of the specific charges and evidence outlined by prosecutors.

In a statement delivered to reporters, Menendez offered some of his first public defense against some of the evidence discovered by investigators during their search of his home, including hundreds of thousands of dollars in cash, which he argued he had on hand for emergencies and described as an “old fashioned” habit derived from his family’s experience in Cuba.

“For 30 years, I have withdrawn thousands of dollars in cash from my personal savings account, which I have kept for emergencies, and because of the history of my family facing confiscation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,” said Menendez. “Now this may seem old-fashioned, but these were monies drawn from my personal savings account based on the income that I have lawfully derived over those 30 years.”

According to the indictment, searches of Menendez’s home and safe deposit box that federal agents conducted in 2022 turned up nearly $500,000 in cash, including in envelopes inside jackets emblazoned with Menendez’s name. Prosecutors say some of the envelopes had the fingerprints or DNA of one of the business contacts from whom the senator is accused of taking bribes.

Menendez has been charged with three alleged crimes, including being on the receiving end of a bribery conspiracy. The conspiracy counts also charge his wife and three people described as New Jersey associates and businessmen.

The group is accused of coordinating to use Menendez’s power as a US senator to benefit them personally and to benefit Egypt.

On Monday, Menendez defended his record as it relates to Egypt, saying, “If you look at my actions related to Egypt during the period described in this indictment, and throughout my whole career, my record is clear and consistent in holding Egypt accountable for its unjust detention of American citizens and others, its human rights abuses, its deepening relationship with Russia, and efforts that have eroded the independence of the nation’s judiciary, among a myriad of concerns.”

The New Jersey senator has denied wrongdoing and pushed back on calls to resign.

On Monday, Menendez accused those who “rushed to judgment” of doing so for “political expediency.” Multiple members of Congress’ New Jersey delegation have called on him to resign, and Rep. Andy Kim has announced that he is running for Menendez’s seat.

“I recognize this will be the biggest fight yet,” Menendez said, referencing the legal battle ahead. “But as I have stated throughout this whole process, I firmly believe that when all the facts are presented, not only will I be exonerated, but I still will be New Jersey’s senior senator.”
