WASHINGTON – In the days before he left office, President Donald Trump instructed that his family get the best security available in the world for the next six months at no cost to them – the protection of the U.S. Secret Service.

According to three people briefed on the plan, Trump issued a directive to extend post-presidency Secret Service protection to his four adult children and two of their spouses, who were not automatically entitled to receive it.

Trump also directed that three key aides leaving government continue to receive the protection for six months: former treasury secretary Steven Mnuchin, former chief of staff Mark Meadows and former national security adviser Robert O’Brien, two people familiar with the arrangement said.

Under federal law, Trump, his wife, Melania Trump, and their 14-year-old son are the only members of his immediate family entitled to Secret Service protection after they leave office. The couple will receive it for their lifetimes, and Barron is entitled to protection until he turns 16.

Former vice president Mike Pence and his wife, Karen Pence, will also receive continued Secret Service security for the next six months under the same law governing protection.

But Trump wanted every family member who had been protected by the Secret Service during his administration to be covered for six additional months, according to the people familiar with his directive, who spoke on the condition of anonymity to describe security arrangements.

That means the expensive, taxpayer-funded security will continue for daughter Ivanka Trump and her husband, Jared Kushner; son Donald Trump Jr.; son Eric Trump and his wife, Lara Trump; and daughter Tiffany Trump.

The 24-hour protection will focus on Trump’s grown children, though his grandchildren will receive protection that derives from being in proximity to their parents.

A former Trump White House spokesman declined to comment. A spokeswoman for the Secret Service also declined to comment, saying the agency does not discuss the individuals it protects.

A president can order Secret Service protection for any person he chooses, but it is highly unusual for a departing president to provide 24-hour security to relatives who are adults long past their college years. It’s unclear what precedent there is for a departing president to extend this same protection to aides after they have left his administration.

Former Trump White House spokesman Judd Deere declined to comment on Trump’s directives before he left office.
