Jurors in the bribery trial of Sen. Bob Menendez and co-defendant Salomon Melgen is deadlocked, according to a report.

"Menendez jury deadlocks, judge orders them to keep trying to reach a verdict," CNN anchor Jake Tapper tweeted, crediting reporter Laura Jarrett‏.

Jarrett wrote on Twitter, "Judge tells jurors to clear their heads and come back tomorrow."

Melgen, a Florida ophthalmologist who has other business interests, is accused of offering Menendez free flights and gifts in exchange for help getting visas for girlfriends and the senator's assistance in a Medicare billing dispute and a port contract in the Dominican Republic.

Melgen was convicted in April of fraud for overbilling Medicare by as much as $105 million.

Before being indicted 2015, Menendez repaid Melgen nearly $70,000 for three unreported flights aboard Melgen's plane after ultimately unconfirmed reports that the men patronized prostitutes in the Dominican Republic.

Prosecutors uncovered other flights, in addition to numerous vacations taken by Menendez at Melgen's Caribbean villa in the Dominican Republic and on his dime at a hotel room in Paris, along with legal defense and campaign donations.

Menendez and Melgen argue they were close friends who were doing each other favors, not committing crimes.
