BEDMINSTER TOWNSHIP, N.J. — It was important for Sandra Diaz to be invisible.
Before entering the Trump family villa, she would tie back her hair, pull on latex gloves and step into delicate paper shoe coverings. She knew not to wear makeup or perfume that might leave the faintest trace of her presence.
As Donald Trump’s personal housekeeper, Diaz was dealing with a fussy celebrity owner who presided like a monarch over the Trump National Golf Club Bedminster long before he was elevated to president. She was an immigrant from Costa Rica working illegally for Trump with a fake Social Security card she had bought for $50. Being invisible was her life’s work.
