In 2015, Chambers introduced LB268, repealing the state's death penalty. The measure passed the legislature over Governor Pete Ricketts's veto. Following the veto, a petition drive was undertaken to reject the bill and maintain capital punishment. Enough signatures were secured to suspend LB268 until the November 2016 general election; in the election, 60% of the votes cast favored rejecting the repeal and keeping the death penalty.Duggan, Joe, Paul Hammel, and Martha Stoddard (May 28, 2015).
