Democratic U.S. Sen. Bob Menendez of New Jersey defiantly pushed back against federal corruption charges on Monday, saying cash authorities found in his home was from his savings account and was on hand for emergencies, it wasn’t bribe proceeds.

He said he believed that he’d be exonerated and that prosecutors sometimes get the facts wrong.

“I recognize this will be the biggest fight yet, 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 the New Jersey’s senior senator,” Menendez said at Hudson County Community College’s campus in Union City, where he grew up. He did not respond to questions and did not address whether he will seek reelection next year.

Addressing allegations in the indictment unsealed Friday that authorities found cash stuffed in envelopes and clothing at his home, Menendez said the funds were draw from his personal savings account and stemmed his parents fear of confiscation of funds from their time in Cuba.
