The newest sanctions would bar nine American officials from entering Russia. The list includes House Speaker John Boehner, R-Ohio; Senate Majority Leader Harry Reid, D-Nev.; and Sen. John McCain, R-Ariz.
Just as Vladimir Putin's government shrugged off U.S. sanctions earlier in the week, so did the Americans targeted by Moscow.
"The Speaker is proud to be included on a list of those willing to stand against Putin's aggression," Boehner spokesman Michael Steel said in a statement.
McCain tweeted that he's "proud to be sanctioned by Putin."
As each side imposes sanctions, left unclear is whether any of them will have an effect on the standoff over Russia's widely challenged annexation of Crimea. (+ FoxNews video) » | FoxNews with The Associated Press | Thursday, March 20, 2014
