“People need to ask: Why is a foreign country trying to give this massive gift to Donald Trump?” Lieu said. “Think about the precedent it would set.”

Trump has stressed that the plane would initially be donated to the Defense Department. After his term ends, he says it would be donated to a future presidential library.
