Melania Trump is the first immigrant to reside at the White House, unless you count Louisa Catherine Johnson Adams as an immigrant. She was born abroad to parents who were both US citizens.
Could you imagine the fawning of the media if there was a Democrat president in the White House with an immigrant wife? Won’t happen with Melania, because she’s married to a Republican and is too much prettier than the “second Jackie O”, Barak Obama’s husband Michael.
