The White House on Friday refused to comment on reports that Russian President Vladimir Putin's personal wealth could be targeted if the West were to move ahead with additional sanctions over Ukraine.
"I'm not going to get into foreshadowing particular individuals or entities that the United States may target," national security adviser Susan Rice told reporters at the White House. "But let me just say we've been clear that there are additional individuals, officials, close associates of senior leadership, oligarchs and those entities that they are associated with that remain very much potential targets of additional sanctions."
