Melania Trump’s announcement that she was autographing and auctioning a hat for personal profit with two other items － for an opening bid of $250,000 － has left even those who know the former first lady well puzzling over her decision.
Mrs.Trump always viewed the role differently than most of her recent predecessors. Now her high-priced opening bid is recalling her same preoccupation with doing what she wants instead of concerning herself with the American public, and it’s opening the former first lady up to renewed criticism.
"(Selling her hat) lends credence to the notion that the Trumps were always shameless about making money and that Melania keeps proving that she is a Trump through and through," said CNN contributor Kate Andersen Brower.
