Dems condemn Trump's jet deal, call $400M gift 'unconstitutional'

"We shouldn't do it," Sen. Peter Welch, D-Vt., said, adding that, "We can build our own planes for security."

"It's smelly enough that he should come to Congress. It looks and feels an awful lot like an emolument, and he and his library will end up getting a personal benefit out of it," Sen. Sheldon Whitehouse, D-R.I., told Fox News Digital when asked if Trump's deal needed congressional approval. 

On Wednesday morning, Trump signed a series of agreements with Qatar's Emir Sheikh Tamim bin Hamad Al Thani in Doha, Qatar, which included a Qatari purchasing agreement on 160 American Boeing planes, defense agreements and a declaration of cooperation between the countries. 

Trump defended his decision to accept the Qatari jet on Tuesday, saying it would be "stupid" not to and emphasizing that he accepted it on behalf of the U.S. government, not himself. 

"This big savings will be spent, instead, to MAKE AMERICA GREAT AGAIN! Only a FOOL would not accept this gift on behalf of our Country. Thank you for your attention to this matter!" Trump added.
