WASHINGTON (Reuters) - U.S. Director of National Intelligence James Clapper said on Thursday that Russia has a “long history” of interfering in elections, but that U.S. officials had never encountered activity like its efforts during the 2016 U.S. campaign. “The Russians have a long history of interfering in elections.

However, he added, “I don’t think we’ve ever encountered a more aggressive or direct campaign to interfere in our election process than we’ve seen in this case.”
