Washington (CNN) Long lines and staffing issues have hit airports around the country as the partial government shutdown is in its fourth week.

Atlanta's Hartsfield-Jackson, the world's busiest airport, said on Monday that it was struggling with short staffing from the Transportation Security Administration as footage of the lengthy security lines there hit social media.

"Mondays are always busy days for us at Hartsfield-Jackson, but I can tell you that we are down a few security lanes because of the shutdown," Elise Durham, the airport's communications director, told CNN.

Durham said that although the lines at the Atlanta airport were long, they were moving.
