The Transportation Security Administration saw a higher than usual drop in staff during the partial government shutdown and its aftermath last year when several thousand security checkpoint officers abandoned the agency, according to federal data obtained by the Washington Examiner.

Attrition numbers provided by TSA show 2,928 officers left the agency from December 2018 through March 2019, which was 9% higher than the same period a year earlier. The partial shutdown stretched from Dec. 22, 2018, through Jan. 25, 2019, and was the result of President Trump and lawmakers not reaching a funding agreement on border fence projects.
