Sims declined to comment. An ODNI spokesperson didn’t immediately respond to a request for comment.
POLITICO previously reported that Trump was incensed by Sims’ book, with several current and former White House officials having described the president as “very pissed off” and “really hopping mad” upon reading early excerpts and leaks of its text.
“A low level staffer that I hardly knew named Cliff Sims wrote yet another boring book based on made up stories and fiction,” Trump tweeted in January 2019. “He pretended to be an insider when in fact he was nothing more than a gofer. He signed a non-disclosure agreement. He is a mess!”
In his lawsuit against Trump, Sims argued that the federal government was seeking to penalize his “First Amendment right to disclose unclassified information regarding which he learned during his tenure as a federal employee.” The lawsuit was eventually dropped.
After a brief legal dispute, Sims and Trump reconciled because Trump eventually realized that the book was ultimately flattering toward him while offering a stinging critique of some of his senior staff, according to the official.
Since leaving the White House in mid-2018, Sims also remained a close ally of the Trump family, especially son-in-law Jared Kushner and Donald Trump Jr., as well as counselor Hope Hicks.
Sims’ attorney for the lawsuit was Mark Zaid, who has represented a number of federal government whistleblowers alleging misconduct by the Trump administration.
