VILNIUS (Reuters) - U.S. President Donald Trump has expressed support for an undivided Ukraine in a letter to Lithuania's president that is likely to be welcomed in Kiev and by the NATO alliance. "Your support for the sovereignty and territorial integrity of Ukraine, as well as your efforts to increase energy diversification, advance our shared goal to enhance European and regional security," Trump wrote in a Feb. 8 letter posted on the website of the U.S. embassy in Vilnius.
