The Transportation Security Administration said Monday it will begin shifting airport security screeners from other parts of the country to cover rising absenteeism in major airports that appear to be caused by the partial government shutdown.

“TSA Federal Security Directors, in concert with the airport & servicing airlines, will announce when lane closures occur so passengers can plan accordingly. @TSA will reallocate screening officers on a national basis to meet staffing shortages that cannot be addressed locally,” TSA Assistant Administrator for Public Affairs Michael Bilello said in a statement Monday afternoon.
