Does the President have any input on who serves on the PPD?
Limited. He can ask to have someone removed and he (and his family) can express an interest in one of the existing Secret Service Agents within the general detail but that’s about it. If he picked a Secret Service Agent from outside the general detail there is a lot of specialized training after the person has been cleared for the job. I’d bet on it being longer than a year for an experienced Secret Service agent to get through the approval process and training to be allowed on the detail. Right now it might be easier since there are going to be some openings. I’m sure the Secret Service would give a lot of deference to his desires for someone to join his detail and especially the body detail.
