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.

Brit Hume warned on Fox News Monday that Qatar’s donation of a luxury aircraft to the U.S. government for President

The plan raises substantial ethical issues, given the immense value of the lavishly appointed plane and that Mr. Trump intends to take ownership of it after he leaves office.

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."

Any donation to this government is always done in full compliance with the law,” White House press secretary Karoline Leavitt said Monday.

The president grew angry when questioned about the ethical implications of accepting a luxury jetliner from a foreign government.

Sources told ABC News that Attorney General Pam Bondi and Trump's top White House lawyer David Warrington concluded it would be "legally permissible" for the donation of the aircraft to be conditioned on transferring its ownership to Trump's presidential library before the end of his term, according to sources familiar with their determination.

President Donald Trump defended Qatar gifting the U.S. a jet to use as Air Force One as the new fleet is still under construction.

Senate Majority Leader John Thune and GOP firebrand senators are among those voicing discomfort with the deal.
