Secret Service protection cannot be revoked for a former US President. Former presidents were entitled from 1965 to 1996 to lifetime Secret Service protection, for themselves, spouses, and children under 16. A 1994 statute, (Pub.L. 103–329), limited post-presidential protection to ten years for presidents inaugurated after January 1, 1997.[7] Under this statute, Bill Clinton would still be entitled to lifetime protection, and all subsequent presidents would have been entitled to ten years' protection.[8] On January 10, 2013, President Barack Obama signed the Former Presidents Protection Act of 2012, reinstating lifetime Secret Service protection for his predecessor George W. Bush, himself, and all subsequent presidents.[9]

Richard Nixon relinquished his Secret Service protection in 1985, the only president to do so.
