Thousands of pages of documents stolen from the Democratic Congressional Campaign Committee in 2016 were used by Republican congressional campaigns to undermine the validity of several Democratic House members, the New York Times reported.

The Russian influence operation made secret campaign documents public, which led to complications in nearly a dozen House races around the country. Kelly Ward, the executive director of the D.C.C.C. said that it was “an attack by a foreign actor that had the intent to disrupt our election, and we were the victims of it.”

House races in Pennsylvania, New Hampshire, Ohio, Illinois, and North Carolina were all put at risk due to the document dump.

Representative Ben Ray Luján, Chairman of the D.C.C.C., wrote a letter to his Republican counterpart. In it, Luján said, “the N.R.C.C.’s use of documents stolen by the Russians plays right into the hands of one of the United States’ most dangerous adversaries. Put simply, if this action continues, the N.R.C.C. will be complicit in aiding the Russian government in its effort to influence American elections.”

Nancy Pelosi, then the House Minority Leader, wrote a similar letter to then House Speaker Paul Ryan to no response. However, the Congressional Leadership Fund, a “super PAC” tied to Ryan, used stolen material to attack Democrat Joe Garcia in his campaign in Florida.
