Melania Trump outsourced writing her own 'thank you' notes to the White House residence staff

(CNN) First lady Melania Trump did not write her own "thank you" notes to the White House residence staff who have cared for her and her family for the last four years, according to two sources with knowledge of the notes and Trump's handling of them.

The 80 or so staff who received the type written notes were under the assumption the first lady had written them herself. Instead, Trump tasked a lower-level East Wing staffer with writing them "in her voice," and she signed her name.

Several sources familiar with Trump's activities, or lack thereof in recent weeks, have described the first lady as being "checked out," that she "just wants to go home," and is "not sad to be leaving" Washington and the White House.

One of the sources discussing the "thank you" notes with CNN said it is customary for first ladies -- and occasionally presidents as well -- to write cards or short letters of gratitude to members of household staff, especially the ones whom they get to know extremely well. Much of the correspondence includes personal anecdotes and the letters become "cherished keepsakes" for the residence staff, says the source.

The butlers, cooks, housekeepers, ushers and maintenance workers do not typically turn over with each administration and many have been working at the White House for a decade or more.
