From a New York Times story by Eric Lipton and Maggie Haberman headlined “She Took the White House Photos. Trump Moved to Take the Profit.”:

As President Donald J. Trump’s tenure came to an end, the chief White House photographer, who had traveled the world with him and spent countless hours inside the White House snapping pictures, notified Mr. Trump’s aides that she intended to publish a book collecting some of her most memorable images.

This was hardly a radical idea: Official photographers from every White House since President Ronald Reagan’s have published their own books. Barack Obama and George W. Bush were so supportive that they wrote forewords for them.
