Goodbye Iowa. On the road home. Gotta get back to writing. Will try to tweet in useful ways. pic.twitter.com/DCbu3Yvqt3— Reinhold Niebuhr (@FormerBu) October 23, 2017

According to CNN, "The account has also tweeted out scenic pictures from West Point, Gettysburg and around Iowa."
Comey is also penning a book about leadership and "yet-unheard anecdotes" from his career, set to come out in next year's spring.
Earlier in May, the former FBI director was fired from his post by President Donald Trump amid an investigation of a likely collusion between the Trump campaign and the Russian officials.
