Sen. Jeanne Shaheen (D-N.H.) is urging the Senate Foreign Relations Committee to hold a hearing on Russia’s reported involvement in U.S. elections.

“I believe a full committee hearing on this issue, perhaps supplemented by a classified briefing, would be beneficial both to members of the committee and the constituents they represent,” Shaheen wrote in a letter Thursday to Sens. Bob Corker (R-Tenn.) and Ben Cardin (D-Md.), the chair and ranking member of the committee, respectively. Neither office had immediate comment on the letter.

The intelligence community has coalesced around the belief that the Russian government was behind the hacking of the Democratic National Committee. The stolen emails released from that incident seemed to show staffers tipping the scales in the primary toward Hillary Clinton, even though they were supposed to remain neutral. Soon after, Rep. Debbie Wasserman Schultz (D-Fla.) stepped down from her position as DNC chair.

Last month, the FBI also issued a nationwide alert urging states to examine the vulnerability of their voting systems. Hackers have targeted systems in both Illinois and Arizona, and the FBI informed the latter state in June that Russian hackers were behind the breach there.

“These developments raise the sobering possibility that Russia is employing the tactics it has used to influence elections in places like Ukraine and Georgia, this time in the United States,” Shaheen wrote.
