WASHINGTON — Rep. Joe Crowley collapsed Wednesday while protesting President Trump’s immigration policies not far from the White House.

The Queens Democrat sunk down to the pavement in downtown DC. Video shows Crowley sitting on the ground, hunched over and rubbing his eyes and red face.

A police officer ordered crowds to “clear the area” so Crowley, 56, would have space for medical attention. Someone gave him a bottle of water and he drank it while sitting on the pavement, holding his eyeglasses.

Crowley didn’t ride in an ambulance to seek hospital care, but he had his blood pressure checked and is now “fine,” according to his office.

Reporters on the scene spotted Crowley get up and walk to a nearby hotel to get fanned off.

A spokesperson for Crowley, the No. 4 Democrat in the House, said he suffered from a bout of “heat exhaustion” brought on by the hot, muggy weather and long day marching.

Crowley was part of a group of Democratic lawmakers and activists protesting the policy of separating undocumented children and their parents at the border.

Crowley let everyone know he was OK on Twitter.

“Thanks for everyone’s concern -doing fine now,” Crowley tweeted. “Wish I could say the same for the children and parents at the border.”
