Donald Trump Jr. hits Michael Moore for suggesting Mar-a-Lago open as shelter: ‘Narrative!’

Donald Trump Jr. on Sunday shot back at documentary filmmaker Michael Moore after he questioned whether President TrumpDonald John TrumpGillibrand urges opposition to Kavanaugh: Fight for abortion rights 'is now or never' Trump claims tariffs on foreign nations will rescue US steel industry: report Bannon announces pro-Trump movie, operation team ahead of midterms: report MORE's Mar-a-Lago resort had opened up as a shelter to be used during Hurricane Irma.

"It's on an island on both the ocean & intercostal and in a mandatory evacuation zone... probably not the best idea, but you know, narrative!" Trump Jr. tweeted.

His tweet comes in response to Moore, who tweeted on Friday before the storm battered Florida: "Has he opened up Mar-a-Lago as a shelter yet?"

Irma made landfall twice on Sunday, first as a Category 4 storm and then again as a Category 3, as it tore through Florida.

The expectation of the hurricane led to one of the biggest evacuations in U.S. history, with millions leaving their homes to escape the storm. It brought heavy winds and flooding to the region and left millions of people without power. Shelters were opened across the state.

On Monday, Irma was downgraded to a tropical storm, but officials are warning of continued dangers.

President Trump said Sunday he plans to visit Florida "very soon."
