Secretary of State Marco Rubio will travel to the Caribbean country of St. Kitts and Nevis this week to reassert the Trump administration's interests in the Western Hemisphere just a month after the U.S. military operation that removed then-Venezuelan President Nicolas Maduro from power. With the eyes of much of the world on the U.S military buildup in the Middle East and President Donald Trump's threats to attack Iran, Rubio will make a one-day visit to St. Kitts on Wednesday to participate in a summit of leaders from the Caribbean Community, the State Department said.
