Paul Ryan: 'Russians engaged in a sinister and systematic attack on our political system'

House Speaker Paul Ryan, R-Wis., said Friday that the Russians took part in a “sinister and systematic attack” on the U.S. political system, after Deputy Attorney General Rod Rosenstein announced indictments of 13 Russian nationals and three Russian entities for meddling in the 2016 election.

“We have known that Russians meddled in the election, but these indictments detail the extent of the subterfuge,” Ryan said of the indictments stemming from special counsel Robert Mueller’s investigation.
