The White House defended the United Nations Relief and Works Agency Thursday as Republican lawmakers are demanding investigations into reports that the aid body’s staff has embedded with Hamas and aiding the terror organization in Gaza and throughout the Middle East.

National Security Council spokesman John Kirby defended the agency, however, when asked if Republicans’ calls to investigate the agency have shifted the administration’s “strategy” regarding the organization. Former President Donald Trump forcibly cut ties with UNRWA in 2018, but the group again began receiving money from the U.S. after President Joe Biden entered office in 2021. Since that time, the U.S. has sent UNRWA more than $700 million.

“The U.N. relief agency does important work. In fact, they’re doing a lot of heavy lifting right now in terms of trying to get food, water, medicine to the people of Gaza all up and down the strip. They’re doing a lot of work, and they’re doing it in harm’s way,” Kirby told reporters. “You can’t hold them accountable for the depredations of Hamas and the way Hamas uses civilian infrastructure, including hospitals, for command and control or storage of weapons for the holding of hostages.
