A House Committee is expected to launch an investigation into a United Nations agency that provides aid to Palestinians for alleged ties to Hamas, according to a report.

The House Foreign Affairs Committee is planning to investigate the United Nations Relief and Works Agency for Palestinian refugees in the Near East, which is also known as UNRWA, according to the New York Post.

Rep. Darrell Issa, R-Calif., told the outlet that there's evidence of a connection between the UN agency and Hamas.

"There is extensive evidence of a troubling connection between UNRWA and Hamas, and it is far deeper than was known," Issa said. "Congress must now investigate and uncover the extent of what UNRWA knew, what it did, and what it may be hiding from the world."

The State Department under former President Trump cut ties with UNRWA in 2018, with the agency calling the organization an "irredeemably flawed operation."

However, President Biden reestablished the relationship in June 2021.
