Bradley and Selina Meyer maintain a good friendship, and it is suggested that they have known eachother for many years. He also maintains a distant and formal friendship with James Whitman, a former Secretary of State. It is later revealed that Bob suffers from Alzheimer's.
Season 5 Edit
Bradley is hired after the O'Brien campaign hires Whitman for the Nevada Recount, and they need someone to take charge. In The Eagle, he begins displaying more erratic and concerning behaviour, forgetting peoples names (calling Amy Brookheimer "Jamie") and what time of day it is.
Later, during a meeting with James Whitman to discuss extending the recount, Bradley abandons the meeting to contact Meyer. Whilst on video conference to President Selina Meyer from a storage cupboard, he becomes confused at the computer screen, and later refers to Selina as "Mr. President", making dismissive remarks about the idea of a woman holding the office. Afterwards, he takes a taxi away from the meeting building, much to the shock of Dan Egan. After discovering that Bradley has Alzheimers, Meyer decides that instead of firing him (because he knows devastating private news within the administration), she will send him to the basement to be the "Cyber-Security Czar".
