Ex-President Richard Nixon also rejected Secret Service protection, saying it would save the public money.
"That is a very, very slippery slope to go down as far as the Secret Service is concerned," said former Secret Service agent Joe Funk, a 21-year veteran of the Secret Service who served on the details of presidents George H. W. Bush and Clinton.
But the courts rejected their argument that Secret Service agents deserve special confidentiality privileges.
