As Iowa’s newest congressman, Zach Nunn has spent restless nights in Washington, D.C., lying on an air mattress plopped on the carpeted floor of his congressional office.

For the father of six children, it’s a cheaper alternative than renting an apartment. Besides, he’s used to it.

Back home in Bondurant, Iowa, Nunn and his wife, Kelly, have traded places sleeping on the floor next to his youngest daughters’ bedsides to comfort the two girls, 2-year-old Aliya and 3-year-old Jayna.
