The Muslim Brotherhood was founded in Egypt in the late 1920s and has since morphed into a pan-Islamic organisation with over a million followers worldwide across 70 nations. It is considered a terrorist organisation by multiple countries, including Russia, Egypt, Saudi Arabia, and the United Arab Emirates.

White House Press Secretary Sarah Sanders said in a statement that the Trump administration was working on blacklisting the Muslim Brotherhood* by assigning it the status of a foreign terrorist organisation.

"The president has consulted with his national security team and leaders in the region who share his concern, and this designation is working its way through the internal process", Sanders said, as quoted by The New York Times.

The report suggests that US Secretary of State Mike Pompeo, as well as National Security Advisor John Bolton, have favoured the idea.

Nevertheless, the US Department of Defence, along with several national security and diplomatic officials, has expressed opposition to the move, suggesting a more limited step instead.
