Members of the US Congress are moving quickly to designate the Muslim Brotherhood as an official terrorist organization.

Sen. Ted Cruz (R-TX) announced on Tuesday that he will reintroduce an updated version of the Muslim Brotherhood Terrorist Designation Act.

“In the coming days, I will be circulating and re-introducing a modernized version of the Muslim Brotherhood Terrorist Designation Act, which I have been pushing for my entire Senate career,” he posted on X/Twitter. “The Muslim Brotherhood used the Biden administration to consolidate and deepen their influence, but the Trump administration and Republican Congress can no longer afford to avoid the threat they pose to Americans and American national security.”

Meanwhile, Rep. Jared Moskowitz (D-FL) sent a letter to the White House on Tuesday asking US President Donald Trump to open an investigation into the Muslim Brotherhood, saying that the group maintains “a documented history of promoting extremist ideologies.”

“Egypt, Saudi Arabia, and the UAE all declared the Muslim Brotherhood an FTO [foreign terrorist organization] over a decade ago, and France is considering its own action. Following suit would help the US disrupt the Muslim Brotherhood’s ability to recruit and finance terror around the globe,” Moskowitz wrote on X/Twitter.

The push to proscribe the Muslim Brotherhood gained momentum last month, when the Institute for the Study of Global Antisemitism and Policy (ISGAP) organized a meeting to help members of Congress develop “strategies to ban the growing threat of the Muslim Brotherhood in the United States,” the research group said in a press release.

“The Muslim Brotherhood appears to be the intellectual inspiration behind all Islamist groups (and their jihadist offshoots) that operate today, such as ISIS, al Qaeda, and Hamas,” ISGAP wrote in a 2023 report. “Sunni jihadist groups are grounded in the firm ideological roots that key MB [Muslim Brotherhood] ideologues pioneered in the last century.”

Hamas, the internationally designated terrorist group that has ruled Gaza for nearly two decades and perpetrated the largest single-day massacre of Jews since the Holocaust with its invasion of Israel on Oct. 7, 2023, is a Palestinian offshoot of the Muslim Brotherhood. Both Cruz and Moskowitz noted that Hamas is a “branch” and an “affiliate” of the global Islamist movement.

While several countries in the Middle East have already classified the Muslim Brotherhood as a terrorist organization, the United States has yet to do the same, despite several attempts by Congress over the years. During Trump’s first term in office, officials in both the White House and Congress took initial steps toward sanctioning the group’s international branches, but a formal designation was never finalized.

US lawmakers believe they have identified multiple pathways to economically cripple the internationally designated terror organization. Congress could combat the Muslim Brotherhood by designating it a Foreign Terrorist Organization (FTO) or placing it on the Specially Designated Global Terrorist (SDGT) list. Both options would levy heavy penalties on the group through methods such as freezing its assets or sanctioning its leadership.
