In 1987 Moyers produced and hosted a scathing documentary, The Secret Government: The Constitution in Crisis, covering the infringement on the limitations on government and the executive branch provided by the Constitution. It considered U.S. foreign policy and militarism historically and recently, centering on the Iran–Contra affair. It was harshly rebuked by conservatives and continuing into the 1990s was used by Republicans as a reason to threaten the funding of the Corporation for Public Broadcasting and PBS.
