Nauta, 40, who served as a military valet in the White House and has stayed by the former president’s side, even while emerging as a critical witness in the Justice Department investigation of Trump’s handling of classified documents at Mar-a-Lago, his Florida home and private club. Nauta, whose full first name is Waltine, was known in the White House for his quiet on-the-job demeanor and ability to stay out of messy internal and partisan squabbling. Nauta enlisted in the U.S. Navy in 2001 and was promoted from the White House mess not long after Trump took office. One of six siblings, he grew up in Agat, a rural village with a population of about 4,515, located in the southwest part of Guam.
