The manufactured outrage is quite amusing on this thread; HOWEVER, the jet from Qatar is NOT a gift to Trump, but instead is a gift to "the American public"- at least for now.
A quick Google search reveals that under Federal law, an executive branch official, including the POTUS, must disclose any gift from a foreign government and valued at $480 or more.
First important point: Gifts from foreign officials/ governments many times MUST be accepted by the POTUS as an act of good will, as foreign relations comes into play that practically require the POTUS to accept the gift (although exceptions exist, such as I'm sure FDR could've refused a gift from Hitler that was a gold statue of him & made from melted gold teeth from Jews who were murdered, etc).
Second important part: Whenever a POTUS' term ends, those foreign gifts not kept/ utilized are deposited into a public registry, as the gifts are owned BY THE AMERICAN PUBLIC during the POTUS' term & thereafter. For those gifts from foreign officials/ governments the POTUS decides to keep, such "is not bribery: A president can keep items to be displayed at their "presidential center", & in so doing, the item remains PUBLICLY OWNED BY US CITIZENS!!
Lastly, if the POTUS wants to keep a foreign gift all to themselves that exceeds the aforesaid monetary threshold, provided they've executed the necessary paperwork that's recorded in some registry that's devoted to presidential gifts AND pay taxes on the gift's FMV, then the POTUS can keep the item for themselves; alternatively, IF Congress convenes & ratifies the foreign donation, the POTUS can keep the gift without paying anything for it (but they still must maintain a paper trail required by relevant federal law, like the Foreign Gifts and Decorations Act of 1966 & subsequent legislation).
So please, stop the faux outrage about this plane from Qatar, ESPECIALLY if you weren't outraged by Hunter getting millions from Burisma &/or all those lucrative contracts or donations to Joe's brother, provided both pinched off 10% 'for the Big Guy'!!!
