Russian hacking has been more widespread than officials have disclosed, current and former defense officials told NBC News in a weekend report, and could encompass an untold number of Republicans.

“High-profile former officials, political figures, current officials,” one official said in describing targets of the hacking, quantifying the scope as including “hundreds of people” from both parties. “I can’t tell you who the Russians are going to leak information about next … the only thing I can tell you is that there are going to be more leaks.”
