Key witness who says he bribed Bob Menendez continues testifying in New Jersey senator's trial

Washington — A star witness who testified about bribing New Jersey Sen. Bob Menendez will be back on the stand Monday. 

Jose Uribe, a New Jersey insurance broker, told jurors last week that he bought the Democratic senator's wife, Nadine Menendez, a new Mercedes-Benz convertible in exchange for the senator's "power and influence" to stop criminal investigations into his business associates. 

Uribe pleaded guilty in March and agreed to cooperate with prosecutors in the case against Menendez, who has pleaded not guilty and has denied accepting any bribes.
