Washington’s Brotherhood designation perimeter keeps widening, and its legal basis is still unclear

The architecture begins with Executive Order 14362, “Designation of Certain Muslim Brotherhood Chapters as Foreign Terrorist Organizations and Specially Designated Global Terrorists,” signed by President Trump on 24 November 2025 and published at Federal Register Vol. 90, No. 227, p. 55033. On 13 January 2026 the State Department and Treasury jointly designated the Egyptian, Lebanese and Jordanian chapters; OFAC’s recent-actions page for that date records the addition to the SDN List of Muhammad Fawzi Taqqosh (Lebanon, born 1973 in Beirut). On 9 March 2026 OFAC listed the Sudanese Muslim Brotherhood, also known as the Sudanese Islamic Movement, flagging secondary-sanctions risk under section 1(b) of Executive Order 13224 as amended. On 23 July, Treasury release sb0572 designated a senior Egyptian Brotherhood official — named in secondary reporting as Mahmoud al-Abyari — along with three further individuals and three entities, for material support to Hamas.

Counting the two intervening OFAC actions of 21 January and 12 March 2026, referenced by Treasury as predicates in sb0572, that is six discrete federal actions in nine months, moving outward from an executive instrument to national chapters, then to a fourth chapter in the Horn of Africa during the Sudan war, then to named individuals and their charities. What has not been resolved in that time is the legal instrument. Some coverage of the January action describes all three chapters as Foreign Terrorist Organizations; other summaries describe them as Specially Designated Global Terrorists. These are different authorities carrying different material-support exposure for third parties, including European and Gulf charities. The two State Department releases from that day have not, in the reporting reviewed here, been read against each other in public.

Assessment: The interesting thing about this file is the direction of travel: outward and downward, from institutions to individuals to the people who move their money. That is the shape of a sanctions programme being operationalised rather than a political gesture being repeated. But the unresolved FTO-versus-SDGT question is not a technicality — it decides whether a Gulf charity that once wired money to a Jordanian affiliate has a compliance problem or a criminal one. Read the ambiguity as useful to Washington: an unclarified perimeter deters more broadly than a clarified one. Distrust any count of Brotherhood decline built on aggregated summaries of paywalled assessments; and note that the organisation’s Egyptian branch announced a legal challenge on 14 January and, seven months on, no filing has surfaced.
