According to MSNBC tonight:
The head of the Federal Air Marshal Service, Thomas Quinn, has resigned, effective Feb. 3, MSNBC.com has learned.
Quinn announced his plans in an internal agency e-mail late Thursday; he gave no reason for his resignation, or any indication of what he plans to do after leaving the agency.
This news comes at a time of transition for FAMS, which was recently moved from ICE to TSA, and is in the middle of changes to integrate it more closely with the TSA screener workforce and experiment with expanding its purview to sea and land-based transportation modes. It also comes in the wake of the air marshal shooting incident in December, although the article indicates that this resignation is not related to that incident.
Update (1/6): Michelle Malkin’s reaction: “good riddance.”
