• The Iowa Senate voted just before 5 a.m. to pass a bill that would roll back child labor laws. 
• The bill, if passed by the House, would allow teens to work longer hours and serve alcohol. 
• A state labor leader told Insider he thought the bill's early-morning passage was a "disgrace." 

Iowa's Republican-led state senate voted in an early-morning session to roll back child labor laws in the state — allowing teens to work longer hours and to serve alcohol at their jobs. 

The bill passed 32-17 before 5 a.m. local time on Tuesday with two Republicans — Sens. Charlie McClintock and Jeff Taylor — joining the entire Democratic party in opposition of the bill.
