James Comey was questioned by the Secret Service over a social media post that raised concerns of calling for violence against President Donald Trump.

Former FBI Director James Comey deleted a post about seeing shells on a beach that were aligned to read "8647" and has since sparked a wave of jokes and memes online amid the fierce backlash. Newsweek previously reached out to Comey via his book website by email on Thursday.
