Russia imposed personal sanctions Monday on 25 Americans, including actors Sean Penn and Ben Stiller, in response to U.S. sanctions against Russians stemming from the conflict in Ukraine. U.S. Commerce Secretary Gina Raimondo was on the new sanctions list, as were several American senators: Mark Kelly and Kyrsten Sinema of Arizona, Kevin Cramer of North Dakota, Mike Rounds of South Dakota, Rick Scott of Florida, and Pat Toomey of Pennsylvania. Russia’s Foreign Ministry said the group, which also included business leaders, academics and government officials, would be banned permanently from entering Russia.
