U.S. President Donald Trump's plan to accept a $400 million airplane from Qatar raises a raft of questions about the scope of laws that relate to gifts from foreign governments and are intended to thwart corruption and improper influence,

“The Boeing 747 is being given to the United States Air Force/Department of Defense, NOT TO ME! It is a gift from a Nation, Qatar, that we have successfully defended for many years,” Trump said in a post on his social media platform, Truth Social, late on Tuesday, May 13.

Although the ethical and security concerns about the president's jumbo jet gift are blatant, experts tell ABC News that the legal ramifications are more complicated.
