Seeking to intensify pressure on Russia, President Barack Obama on Thursday expanded U.S. economic sanctions against Moscow over its actions in Ukraine, targeting President Vladimir Putin's chief of staff and 19 other individuals as well as a Russian bank that provides them support.
Obama, warning of more costs to come for the Kremlin if the situation worsens, said he also had signed an executive order that would allow the U.S. to penalize key sectors of the Russian economy, including its huge energy business. Officials said Obama could act on that authority if Russian forces press into other areas of Ukraine, an escalation of the crisis in Crimea.
The president said the latest penalties were the result of "choices the Russian government has made, choices that have been rejected by the international community."
"Russia must know that further escalation will only isolate it further from the international community," Obama said, speaking from the South Lawn of the White House.
Russia retaliated quickly by imposing entry bans on American lawmakers and senior White House officials. Among them were Senate Majority Leader Harry Reid, D-Nev., and House Speaker John Boehner, R-Ohio. Obama's senior adviser Dan Pfeiffer and his deputy national security adviser, Ben Rhodes, were also targets of the Russian entry bans.
