Applying for a security clearance can be a stressful thing:
Kieran Shanahan’s unexpected resignation as head of the state’s public safety agency in July came as he appeared to be making long-term plans to remain in the job. There are no clues among the messages that he would resign. Rather, they show Shanahan focused on obtaining clearance from Homeland Security.
On the afternoon of July 22, Shanahan’s assistant sent him a text that said she was working on getting the fingerprinting done. About half an hour later, she told him it would be done at the City-County Bureau of Identification in Raleigh, apparently on that date. Three days later Shanahan resigned, along with Chief Operating Officer Edward “Sonny” Masso. There was no indication that their departures were related.
It would be interesting to find out what happened with this security clearance. But you'd probably have to have a security clearance to find out...
