U.S. Senator Graham says enough is enough on Russian cyber activities

"It is now time for Russia to understand – enough is enough," Republican Senator Lindsey Graham of South Carolina said in the Latvian capital.

Earlier this month, U.S. Republican and Democratic senators including Graham called for a special bipartisan panel to investigate cyber attacks against the United States by foreign countries with a focus on Russia's alleged efforts to influence the U.S. presidential election.

Russian officials have denied accusations of interference in the Nov. 8 election.
