The Trump administration has withdrawn the nomination of Adam Boehler to serve as special presidential envoy for hostage affairs, the White House said on Saturday.

The White House is remaining cautious about Hamas's announcement that they would release Edan Alexander, the last-living U.S. hostage. NBC News' Matt Bradley has more on the potential release and the response from Israeli Prime Minister Netanyahu and the U.

Hamas says it will release American Israeli Edan Alexander and the bodies of four other hostages only if Israel implements their cease-fire agreement.

The White House is denying that it violated a judge’s order Saturday to halt the deportations of Venezuelan gang members to El Salvador, which, if it did occur, would take legal showdowns over the administration’s claims of vast presidential power closer to the edge of a constitutional crisis.

Trump officials said the deportations don’t violate a judge’s order barring use of the Alien Enemies Act for removals -- but also questioned the order’s validity.
