Sen. Bob Menendez (D-NJ), once one of the most powerful Democrats in Congress, is expected to get personal in his second corruption trial, which began Monday with jury selection.

The longtime Democratic senator from New Jersey is expected to dig deep and reveal his penchant for hoarding big gold bars and his wife’s alleged lies and blame his father’s gambling problem and death for decisions that led him down a path that ended in a sprawling 18-count federal indictment, according to court documents.
