U.S. Senate Majority Leader Chuck Schumer said on social media that a bipartisan group of senators visiting Israel was rushed to a shelter in Tel Aviv on Sunday to wait out a rocket attack from Hamas. Schumer posted a photo of himself and Republican Sen. Mitt Romney of Utah in the shelter.

“It shows you what Israelis have to go through. We must provide Israel with the support required to defend itself,” Schumer said on X, the platform formerly known as Twitter.

Schumer, the highest-ranking Jewish elected official in the United States, took the trip to show support for Israel ahead of an expected request from President Joe Biden for Congress to approve wartime funding for Israel as well as Ukraine. Schumer, a Democrat, has said he would also hold discussions with Israeli officials what kind of support the country would need for both military and humanitarian operations.

Republican Sens. Bill Cassidy of Louisiana and Democratic Sens. Jacky Rosen of Nevada and Mark Kelly of Arizona were also on the trip.
