Rep. Elise Stefanik, R-N.Y., and Sen. Tom Cotton, R-Ark., are pressing Treasury Secretary Scott Bessent to investigate the Council on American-Islamic Relations (CAIR), claiming that it may be funded or directed by Hamas or other terrorist groups.

CAIR describes itself as a Muslim civil rights and advocacy organization founded in 1994 with chapters across the U.S.

The request comes as President Donald Trump led a ceasefire in Gaza between Hamas and Israel.

Stefanik and Cotton allege CAIR’s historic ties, public rhetoric and activism raise questions about whether the group’s support for Hamas amounts to material support for terrorism.

The Treasury Department’s Office of Foreign Assets Control, which enforces U.S. sanctions on terrorist groups and their affiliates, has the authority to investigate whether CAIR’s activities violate federal law, the lawmakers said.

CAIR has long denied accusations of supporting Hamas, saying it ‘does not support any foreign organization or government’ and calling such claims ‘false and Islamophobic,’ according to a statement on its website. The group says its mission is to advocate for Muslim civil rights in the U.S.

Stefanik chairs the House Republican Conference, and Cotton sits on the Senate Armed Services Committee. Both have pressed for stricter enforcement of anti-terror finance laws in past oversight efforts.

In July, Stefanik criticized the City University of New York for hiring a former CAIR employee. She called the decision unacceptable to New York taxpayers.

She and Cotton say a Treasury probe would ensure no U.S. assets are used to advance the objectives of Hamas.

‘We urge the department to immediately investigate whether CAIR maintains financial links to Hamas that violate U.S. sanctions,’ they wrote.

CAIR did not immediately respond to a Fox News Digital request for comment.
