Washington Post reporter Carol Leonnig says President Trump froze key federal agencies, including the FBI and Dept. of Defense, whose job it was to investigate and stop threats to national security.

Every time the president of the United States travels, he's accompanied by a cadre of Secret Service agents. Sometimes seen wearing crisp suits, sunglasses and ear pieces, the agents charged with protecting the president present a striking visual. But Pulitzer Prize-winning Washington Post investigative reporter Carol Leonnig says the Secret Service itself is something of a mess.

Wash. Post reporters Carol Leonnig and Philip Rucker discuss presidential rages, erratic decision-making and other troubling tendencies of the Trump presidency. Their new book is A Very Stable Genius.
