Former intelligence officials usually keep their security clearance but rarely use it, sometimes providing advice to successors.
Working on the front lines with Fortune 1000 companies to protect and defend their infrastructure from insider threats, cybercriminal syndicates and state-sponsored actors, I have leaned heavily upon the experiences and wisdom of many of our public servants who have worked for our recent presidents of both political parties.

Sanders was later asked if the clearances for President Barack Obama and Vice President Joe Biden would also be removed, she told reporters "I'm not aware of any plans for that at this point". Comey, who Trump fired as Federal Bureau of Investigation director past year, has said he does not have one, his friend Benjamin Wittes said on Twitter. "I mean, it's a banana republic kind of thing". "This is a free country, we have freedom of speech, we have people giving their opinions, and this is just beyond the pale", he said.
