Qatar's offer of a jumbo jet to Air Force One has renewed anger around the Boeing deal signed by Trump in 2018.

Boeing was supposed to deliver a replacement for Air Force One last year, but significant delays have cost the plane maker billions on the project. They have also drawn ire from the president, who told reporters aboard Air Force One in February that he was “not happy with Boeing” and may purchase a plane elsewhere.

Qatar’s royal family has offered a luxury Boeing 747 for Donald Trump’s use as president. Boeing already has a contract for two new 747s.
