Renee Zellweger is urging people to vote in a new video for OurTime.org.
"There's no reason why you should have to sit on the sidelines," Zellweger says.
In honor of National Voter Registration Day, Our Time has launched a celebrity-backed campaign stressing the importance of voting this November. Usher, Steve Carell, Rachel Zoe and the cast of Workaholics are among those encouraging people to vote in the upcoming election.
