Is it past time for President Trump in 2017 to end the CIA?
President Truman did not trust the OSS and its increasing power.
At the end of WWII, he signed an ExO ending the OSS.
September 20, 1945, President Truman signed Executive Order 9621, terminating the OSS. His Order became effective October 1, 1945. In the days following, the functions of the OSS were split between the Department of State and the Department of War.
The State Department received the Research and Analysis Branch of OSS (originally created by Edward Mead Earle[28]) which was renamed the Interim Research and Intelligence Service or IRIS,[29] headed by U.S. Army Colonel Alfred McCormack. Later it was renamed the Bureau of Intelligence and Research by the State
Department.

The problem of terminating the CIA is that once they don’t exist the bad ones will be even harder to find than they are now.At least now we have some reference to them.
