Melania Trump

 NY Times -  As the weeks pass by at the White House, the corner of the residence long used by first ladies remains dark, because this first lady does not really live in Washington.

Melania Trump vanishes from view for weeks at a time, holing up in Trump Tower in Manhattan or in Florida, where she can lie low at Mar-a-Lago. Administration officials say she is at the White House more often than the public knows, but when exactly, and for how long, these officials will not (or perhaps cannot) say for certain....

That the first lady’s whereabouts is among the most sensitive of subjects in this White House only adds to the intrigue.

“We haven’t seen such a low-profile first lady since Bess Truman, and that’s going way back in living human memory, nearly 80 years ago,” said Katherine Jellison, a historian at Ohio University whose research has focused on first ladies. She said that, like Mrs. Trump, Mrs. Truman spent much of her time running back to “her home base whenever she had the chance.” (In Mrs. Truman’s case, that was Independence, Mo.)

“She just kind of liked her own private world,” Ms. Jellison said.
