Ukraine's President Viktor Yushchenko met Friday with a U.S. congressional delegation that included the two prominent U.S. senators who nominated him for the Nobel Peace Prize. Sen. Hillary Clinton and Sen. John McCain were part of an 11-member bipartisan delegation visiting the Ukrainian capital to discuss ways to strengthen U.S.-Ukrainian relations, the U.S. Embassy said. Clinton, a liberal Democrat and the wife of former President Bill Clinton, and McCain, a conservative Republican, nominated Yushchenko and Georgian President Mikhail Saakashvili for the world's most prestigious award. The prize is given out every fall. In their nomination letter last month, the U.S. senators commended the presidents for winning "popular support for the universal values of democracy, individual liberty and civil rights." Yushchenko and Saakashvili both came to power after mass demonstrations protesting fraudulent votes in their former Soviet republics. Yushchenko has pledged to fight corruption, increase living standards and find a place for his 48-million nation in the European Union. His government has also said that improving ties with the United States would be a priority, along with maintaining Ukraine's historic partnership with Russia. The U.S. delegation was also expected to meet with Prime Minister Yulia Tymoshenko and Parliament speaker Volodymyr Lytvyn.
