• President Trump revised his travel ban, removing Iraq but leaving six other predominantly Muslim nations on a list of those whose citizens are barred from entering the U.S.

Officials said the rewrite was meant to address legal concerns quickly to deal with what they say is a national security threat. But in the Middle East, it is still seen as amounting to a ban on Muslims.

Separately, the White House said Mr. Trump “firmly believes” that former President Barack Obama had him wiretapped, though the F.B.I. director has said otherwise. Since Mr. Trump took office, he and Mr. Obama have criticized each other to an unusual degree.
