The panel told the judge on Monday it was deadlocked, but he told them to keep deliberating.
They spent Tuesday and Wednesday in the jury room without reaching a unanimous verdict against the New Jersey Democrat and his longtime friend, Florida eye doctor Salomon Melgen (MEHL’-genn).
Deliberations began Nov. 6 after a nine-week trial.
The New Jersey Democrat is charged with accepting gifts from Melgen in exchange for using his political influence. Both men deny the allegations.
If the jury can’t reach a verdict, the judge would declare a mistrial and the government would have the option to retry the case.
