NEWARK, N.J. — The jury in the bribery trial of Democratic U.S. Sen. Bob Menendez and a wealthy donor and friend told the judge it couldn’t reach a verdict on Monday on any of the 18 counts against them, prompting the judge to order it to return on Tuesday to continue deliberating.

The development capped a tumultuous day that began with defense attorneys arguing with U.S. District Judge William Walls over a different issue: public comments made last week by a juror who had been excused for a previously scheduled vacation.

The juror told reporters she and others anticipated a hung jury.
