Vice President Joe Biden on Monday launched a high-profile visit to demonstrate the U.S. commitment to Ukraine and push for urgent implementation of an international agreement aimed at de-escalating tensions even as violence continues. Biden planned to meet Tuesday with government leaders who took over after pro-Russia Ukrainian President Viktor Yanukovych was ousted in February following months of protests. The White House said President Barack Obama and Biden agreed he should make the two-day visit to the capital city to send a high-level signal of support for reform efforts being pushed the new government.
