Madeleine Westerhout, President Donald Trump's executive assistant, was "inconsolable" on election night in 2016, according to a new book by the journalist Tim Alberta.

Then a 26-year-old Republican National Committee staffer, Westerhout was soon tasked with assisting Trump's transition team.

"To the amusement of her RNC peers, she was later chosen as the president's executive assistant and now sits just outside the Oval Office," Alberta wrote in "American Carnage."

Westerhout now says she's completely loyal to the president, for whom she says she'd do almost anything, Alberta wrote. And Trump reportedly likes to call her "my beautiful beauty."

A California native and 2013 graduate of the College of Charleston in South Carolina, Westerhout now says she's completely loyal to the president, for whom she says she'd do almost anything, Alberta wrote. And Trump reportedly likes to call her "my beautiful beauty," according to the report on the book.
