Bernie Sanders said he knew Russia was trying this tactic against Democrats during the election

File-This June 23, 2016, file photo shows Democratic presidential candidate Sen. Bernie Sanders, I-Vt., addressing supporters in New York. Sanders says he’ll try to block Senate consideration of a bill that would require nationwide labeling of food with genetically modified products, but with a less stringent labeling requirement than the one included in Vermont’s law. Individual senators can put a hold on legislation, blocking it from coming up for debate unless backers can muster 60 votes. The Vermont independent says he prepared to resort to that tactic.
