'Melania Trump is hiding': Author has trouble serving first lady subpoena over threats

An author who has written four books about President Donald Trump said on Thursday that he's struggling to serve a subpoena to first lady Melania Trump in connection with a lawsuit he filed against her.

Journalist Michael Wolff sued Melania Trump in October after she filed a $1 billion lawsuit against him for “false, defamatory, disparaging, misleading, and inflammatory statements” he made about her connection to disgraced financier Jeffrey Epstein. Wolff said on Thursday's episode of "Inside Trump's Head," a podcast he co-hosts with Joana Coles of The Daily Beast, that he has struggled to serve Melania Trump a subpoena.

"It would appear that Melania Trump is hiding from me,” Wolff said. “It’s quite unclear how you serve a subpoena on someone who has one of the most elaborate security details in the world.”

Wolff said a service company has tried to serve Melania Trump at both the White House and Trump Tower in New York City. However, they have hit roadblocks at both addresses.

“They took the service and then, after they accepted this—somewhere midway in this—we got a call and they were saying, ‘Hey, you’re trying to serve the first lady. We’re not doing that,'” he said. “They’re like, ‘No way are we serving the first lady of the United States.’”
