Trump ordered John Brennan's security clearance be taken away but the OPM didn't remove it so Trump is going close that government agency entirely.
“This is a crisis building for years,” acting OPM Director Margaret Weichert told the Post. Weichert said furloughs are a “last resort we are trying to avoid,” and that “a legislative solution would be the most straightforward answer.”
The administration’s plan is to eliminate the OPM, which manages 2.1 million civilian federal workers, and divide its roles among three other agencies. Recent legislation has already called for its security clearance system to move to the Department of Defense. Most of OPM’s responsibilities would fall under the General Services Administration, and a new GSA deputy who would be appointed by the president to take over for OPM’s current agency director.
