Justice Department nominees won't be confirmed until the Trump administration provides full transparency on "Qatari influence," Senate Minority Leader Chuck Schumer, D-N.Y., announced on Tuesday.

During a press briefing in the White House on Monday, before embarking on a four-day trip to the Middle East, Trump called the donation a "very nice gesture."

The nation of Qatar offered the Trump administration a Boeing 747-8 for use as Air Force One. Trump called the plane a "gift," in a post on his social media site, Truth Social. A representative of the administration clarified that Qatar "has offered to donate a plane to the Department of Defense," not to Trump himself.
