A group of US lawmakers has reintroduced the Muslim Brotherhood Terrorist Designation Act of 2025, legislation that would classify the Muslim Brotherhood as a terrorist organization.

Sen. Ted Cruz (R-TX), who spearheaded the effort, is calling on the Trump administration to designate the Muslim Brotherhood as a Foreign Terrorist Organization (FTO), a move that would trigger sanctions and stricter restrictions on its assets, travel, and financial networks.

The Texas senator described the Brotherhood as “a terrorist organization” that provides material support to proxy entities, including Hamas, a Palestinian offshoot of the global Islamist movement. He cited the group’s extremist ideology and noted Hamas’s Oct. 7, 2023, invasion of southern Israel, describing the attack as “the worst single-day massacre of Jews since the Holocaust” during which “at least 53 Americans” were killed or kidnapped.

“American allies in the Middle East and Europe have already labeled the Brotherhood a terrorist organization,” Cruz said in a statement, urging the US to “do the same, and do so expeditiously.” The bill is co-sponsored by several Senate Republicans, including Sens. Tom Cotton (AR), John Boozman (AR), Rick Scott (FL), Ashley Moody (FL), and Dave McCormick (PA).

Cotton echoed Cruz’s assessment, saying the Brotherhood “preaches death to Israel, the United States, and other Western governments,” and argued that such rhetoric warrants a formal terrorist designation.

In the US House of Representatives, Rep. Mario Díaz-Balart (R-FL) introduced companion legislation, citing similar concerns about the group’s global network and ideological influence.

Labeling the Muslim Brotherhood as an FTO would mark a significant shift in US counterterrorism policy. Such a designation would enable the US government to freeze the group’s assets, impose visa bans, and criminalize support for its activities. It would also likely increase scrutiny of affiliated organizations and individuals both inside and outside the United States.

Governments in Egypt, Saudi Arabia, the United Arab Emirates, Bahrain, and Austria have already banned the Brotherhood, arguing it poses a threat to domestic and regional stability. But critics of Cruz’s bill warn that such a sweeping measure could backfire, potentially targeting progressive political efforts and fueling perceptions of US hostility toward Islamic political participation.

The legislation will now be reviewed by the Senate Foreign Relations Committee. While supporters push for swift passage, its fate remains uncertain amid concerns over diplomatic fallout and domestic civil liberties.
