President Donald Trump and his administration officials continue to say the economy is booming. National Economic Council director Kevin Hassett told CNN's State of the Union that he isn't "buying" the polls that say Americans aren't happy with Trump's handling of the economy, calling it "a classic Democrat move."

An AP/NORC poll released Thursday found 82% of Americans disapprove of Trump's handling of the cost of living heading into the midterm elections, in which Republicans are fighting to keep their majority in both houses of Congress.

The poll showed 73% of Americans disapprove of Trump's handling of the economy, up from a 66% disapproval rate in July.
