US national security adviser John Bolton has canceled his trip to South Korea next week, even as preparations ramp up for a second summit between President Donald Trump and North Korean leader Kim Jong Un.
"Ambassador Bolton has canceled his travel to the Republic of Korea to focus on events in Venezuela," National Security Council spokesman Garrett Marquis said in a statement. Bolton is still planning to travel to Hanoi, Vietnam, with President Trump for the North Korea summit, which starts February 27, he said.
