Minority Leader Chuck Schumer was briefly hospitalized Wednesday morning after he got lightheaded at the gym, his spokesperson told ABC News.

He was treated for dehydration and released Wednesday, the spokesperson said, after going to the hospital “out of an abundance of caution.”

By Wednesday afternoon, the New York Democrat was back at work at the Capitol, the spokesperson said.

“He wants to remind everyone to drink some water and stay out of the heat,” the spokesperson added.

Schumer did not address the hospitalization during a news conference or when he spoke on the Senate floor later Wednesday
