WASHINGTON (AP) — U.S. Sen. Bob Menendez of New Jersey and his wife have been indicted on charges of bribery.

Federal prosecutors on Friday announced the charges against the 69-year-old Democrat nearly six years after an earlier criminal case against him ended with a deadlocked jury. The latest indictment is unrelated to the earlier charges that alleged Menendez accepted lavish gifts to pressure government officials on behalf of a Florida doctor.

The Senate Historical Office says Menendez appears to be the first sitting senator in U.S. history to have been indicted on two unrelated criminal allegations. Menendez faces reelection next year in a bid to extend his three-decade career in Washington, and as Democrats hold a narrow majority in the Senate.

Lawyers for Menendez and his wife haven’t responded to messages seeking comment.

The first time Menendez was indicted, he had been accused of using his political influence to help a Florida eye doctor who had lavished him with gifts and campaign contributions. Menendez appears to be the first sitting senator in U.S. history to have been indicted on two unrelated criminal allegations, according to a list maintained by the Senate Historical Office.

The new charges follow a yearslong investigation that examined, among other things, the dealings of a New Jersey businessman — a friend of Menendez’s wife — who secured sole authorization from the Egyptian government to certify that meat imported into that country meets Islamic dietary requirements. Investigators also asked questions about the Menendez family’s interactions with a New Jersey developer.

Menendez faces re-election next year in a bid to extend his three-decade career in Washington, and as Democrats hold a narrow majority in the Senate.
