After some surprising twists Monday in the corruption trial of U.S. Sen. Bob Menendez, D-New Jersey, some trial watchers are not optimistic about whether jurors will be able to reach a unanimous verdict.

First, four jurors and three alternates raised their hands when U.S. District Judge William Walls of the District of New Jersey asked if they had heard or read comments in the media by a juror who was excused for a vacation on Nov. 9, Evelyn Arroyo-Maultsby.

Later in the day, the jury sent the judge a note saying they were hopelessly deadlocked. Menendez's lawyer, Abbe Lowell, asked for a mistrial. Walls sent the jury home early and instructed them to try again on Tuesday.
