While State Department investigators began contacting former officials around 18 months ago, the probe actually began under President Obama. In recent weeks, the State Department has contacted approximately 130 officials whose emails which went through Clinton's special server have been retroactively classified and may now pose potential security violations, according to the Washington Post.
"This has nothing to do with who is in the White House," said a senior State Department official. "This is about the time it took to go through millions of emails, which is about 3½ years."
The flood of letters which began in August read "You have been identified as possibly bearing some culpability" regarding "security incidents," according to the report.
The list of State officials being questioned includes prominent ambassadors and assistant secretaries of state responsible for U.S. policy in the Middle East, Europe and Central Asia. But it also includes dozens of current and former career bureaucrats who served as conduits for outside officials trying to get important messages to Clinton.
