WASHINGTON (Reuters) -U.S. President Donald Trump on Monday began the process of designating certain Muslim Brotherhood chapters as foreign terrorist organizations and specially designated global terrorists, a move that would bring sanctions against one of the Arab world's oldest and most influential Islamist movements.

Trump signed an executive order directing Secretary of State Marco Rubio and Treasury Secretary Scott Bessent to submit a report on whether to designate any Muslim Brotherhood chapters, such as those in Lebanon, Egypt, and Jordan, according to a White House fact sheet.

It orders the secretaries to move forward with any designations within 45 days of the report.

The Trump administration has accused Muslim Brotherhood factions in those countries of supporting or encouraging violent attacks against Israel and U.S. partners, or of providing material support to Palestinian militant group Hamas.

"President Trump is confronting the Muslim Brotherhood’s transnational network, which fuels terrorism and destabilization campaigns against U.S. interests and allies in the Middle East," according to the fact sheet.

Republicans and right-wing voices have long advocated for and considered terrorist designations for the Muslim Brotherhood.

The Republican president mounted a similar effort during his first term. Months after his second term began, Rubio said the Trump administration was working to designate the movement as a terrorist organization.

Texas Governor Greg Abbott, also a Republican, last week imposed the same designation on the Muslim Brotherhood at a state level.

The Brotherhood was founded in Egypt in the 1920s as an Islamic political movement to counter the spread of secular and nationalist ideas. It swiftly spread through Muslim countries, becoming a major player but often operating in secret.
