Attorneys for Sen. Bob Menendez concluded calling witnesses on Wednesday, opting not to have the New Jersey Democrat take the stand in his own defense as he fights allegations that he traded political favors for gold bars and cash.

While leaving court, Menendez said it did not make “any sense” for him to testify. “From my perspective, the government has failed to prove every aspect of its case,” he said.

A handful of witnesses testified on his behalf, compared to the 30 witnesses called by the prosecution during the trial, which has so far spanned eight weeks.

Menendez’s defense attorneys called his sister and the sister of his wife, Nadine Menendez, to testify on Monday as they sought to show it was not unusual for the couple to keep gold and large amounts of cash in their home.
