The White House late Saturday congratulated Polish Prime Minister Donald Tusk on his election as president of the European Council.
“We look forward to working closely with President Tusk and High Representative Mogherini, as well as Commission President Juncker and all of the new Commissioners,” he added.
Italian Foreign Minister Federica Mogherini was chosen as high representative for foreign affairs and security policy.
The leadership changes come as the European Council is considering more sanctions against Russia over its movement of troops and equipment across the Ukrainian border.
European Union leaders said late Saturday that they would draw up options within a week, according to multiple reports.
“We welcome the European Council's consensus today to show strong support for Ukraine's sovereignty and territorial integrity and to prepare further sanctions for consideration in coming days,” National Security Council spokesperson Caitlin Hayden said in a statement late Saturday.
