Thune said Trump’s plan to accept a $400 million jet from Qatar to serve as his command post in the sky remains a “hypothetical,” raising questions about whether the deal will even go through.

U.S. Senate Democratic Leader Chuck Schumer vowed to block all of Trump's nominees to the Justice Department until the agency reports what it knows about Qatar's offer.

Qatari officials say the plan for Mr. Trump to accept the plane for use as Air Force One while he’s in office is not finalized.
