I don't like what he's doing, but I didn't vote for him. As for Melania, she knew what he was before she married him and married him anyway. She got what she deserved.
Melania married Donald in 2005 and she became "first lady" in 2017.
A more important question is where is she? She has not been seen since she went for a kidney transplant in May 2018.
BTW there is no office named "first lady", contrary to what Wikipedia says. It is a sloppy code phrase made up by reporters because they didn't want to keep saying "president's wife".
