As a cost savings, Congress had ended lifetime security details for former presidents, cutting off Secret Service protection 10 years after a president leaves office. But in the post-9/11 world Congress decided that former chief executives may still be vulnerable and need protection.
President Obama has now signed the repeal. HR. 6620, the "Former Presidents Protection Act of 2012," also gives Secret Service protection to former First Ladies and guarantees agents will continue to shadow children of former Presidents until they become 16 years of age.
