During intelligence briefings, former President Donald Trump was “fact free” and prone to “fly off on tangents,” said James Clapper, former director of national intelligence.

Clapper’s comments come from a recently released CIA publication, Getting to Know the President, which chronicles the relationship between the intelligence community and U.S. presidents during their transition and administration. Written by retired intelligence officer John L. Helgerson, the latest chapter covers Trump and reveals how unprepared and unconventional Trump was. It is important to note, however, that this is not a neutral account, given Trump’s rocky history with the intelligence agencies.
