After months of challenges and controversy, President Trump's travel ban expires Sunday.

Days before the expiration of President Trump’s much-contested travel ban, the White House is reviewing a security report that aides say could serve as the basis of a new, and perhaps broader, version.

The classified report by the Department of Homeland Security, sent to the White House last week, is a study of the available security and intelligence information in countries worldwide.

Based on the findings, Trump could decide to keep the travel ban in place, or either limit or expand it, possibly before Sunday.

The order also stopped all refugee resettlement in the U.S. for 120 days, so that ban would continue in effect for roughly a month more.

The Supreme Court in June had allowed the refugee ban to take effect, with exceptions for refugees who could show a “bona fide” connection to the U.S., along with a revised travel ban for 90 days in the six specified nations.

David Lapan, spokesman for the Department of Homeland Security, said it was “certainly possible” that more countries could come under travel restrictions.

“It’s about the conditions in the countries and the quality of information, and not the political or religious factors,” he said.
