U.S. President Donald Trump is considering a new executive order for a travel ban, he said aboard Air Force One late on Friday, and White House chief of staff Reince Priebus said the administration could still escalate a legal dispute over the first ban to the Supreme Court.

Trump two weeks ago issued an executive order banning entry into the United States to refugees and citizens of seven Muslim-majority countries, triggering nationwide protests and legal challenges.

The fallout from the order exposed divisions within the White House and showed how the Republican administration is struggling to find its bearings after less than a month in power.
