				 "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.
