A document outlining the plans — timed to coincide with the third anniversary of Trump’s January 2017 executive order — has been circulating the White House. But the countries that would be affected are blacked out, according to two of the people, who spoke to The Associated Press on condition of anonymity because the measure has yet to be finalized.

It’s unclear exactly how many countries would be included in the expansion, but two of the people said that seven countries — a majority of them Muslim — would be added to the list. The most recent iteration of the ban includes restrictions on five majority-Muslim nations: Iran, Libya, Somalia, Syria and Yemen, as well as Venezuela and North Korea.

A different person said the expansion could focus on several countries that were included when Trump announced the first iteration of the ban but later removed amid rounds of contentious litigation. Iraq, Sudan and Chad, for instance, had originally been affected by the order, which the Supreme Court upheld in a 5-4 vote after the administration released a watered-down version intended to withstand legal scrutiny.
