Democrats are critical of President Trump's warnings to North Korea.

FOX's Rachel Sutherland reports from Washington:

Democratic Congressman Al Green has this message for President Trump:

(Green) "Allow Congress to weigh in before you decide to engage in a war with North Korea."

In a statement, House Democratic Leader Nancy Pelosi said President Trump's threat of "fire and fury" towards North Korea demonstrates weakness, not strength of purpose.
