On February 5, 2026, Attorney General Ken Paxton filed a lawsuit against the Council on American-Islamic Relations (CAIR) and the Muslim Brotherhood. The suit accused both groups of collaborating as a "radical terrorist organization" seeking to seize governmental control and impose Sharia law. Filed in state court in Collin County, the lawsuit asked a judge to designate CAIR as a foreign terrorist and transnational criminal organization and to bar it from operating or raising funds in Texas. Earlier, Texas Governor Greg Abbott formally designated the Muslim Brotherhood and CAIR as foreign and transnational terrorist organizations under state law. The designation bans both groups from acquiring property in Texas and directs the Attorney General, Ken Paxton, to investigate, dissolve, and revoke CAIR's nonprofit status if warranted. Abbott also ordered probes into CAIR's activities in schools and other institutions, and requested that the U.S. Treasury suspend CAIR's federal tax‑exempt status. He framed both groups as terrorism‑linked and threats to national security.
