Trump: "We'll see what happens" with North Korea summit

President Trump responded for the first time Wednesday to North Korea's threat to cancel next month's summit between Trump and North Korean leader Kim Jong-un, stating that "we'll have to see what happens."

Why it matters: With less than one month until the summit, scheduled for June 12th in Singapore, North Korea's changing tone toward the White House's "maximum pressure" stance appears to be testing the Trump administration's boundaries.
