Briefing Donald Trump as a presidential candidate, president-elect, and president during his first few weeks in office presented the Intelligence Community (IC) with greater challenges than it had faced since the Central Intelligence Agency attempted to provide similar support to President-elect Richard Nixon 48 years before. Trump was unique among the dozen presidents who took office since President Harry Truman began the briefing process in 1952 in that he had never served in the military or any branch of government. As a result, he had no experience handling classified information or working with military, diplomatic, or intelligence programs and operations. Trump had traveled abroad but, by his own account, did not often read. Like Nixon, he doubted the competence of intelligence professionals and felt no need for regular intelligence support. Trump declared that he intended to shake up the executive branch, publicly criticized the outgoing directors of national intelligence and the CIA, and disparaged the substantive work and integrity of the intelligence agencies. From the outset, it was clear that the IC was in for a difficult time.
