A second U.S.-North Korea summit is expected to be held in either January or February, with three sites currently under consideration, U.S. President Donald Trump said Saturday.

Speaking aboard Air Force One, Trump was quoted as saying that said a second meeting with North Korean leader Kim Jong Un will happen soon, with the location and timing continuing to be hashed out as the two sides work toward the goals agreed to at the landmark first summit in Singapore in June.

Media pool reports quoted Trump as saying that he and Kim are "getting along very well" and have a "good relationship," and that at some point he'd like to invite the North Korean leader to the United States.
