LINCOLN, Neb. (AP) — Nebraska’s longest-serving lawmaker is promising to tie up the rest of this year’s legislative session with filibusters to punish his colleagues for decisions he opposed.

Sen. Ernie Chambers of Omaha chastised senators on Wednesday for rejecting a bill to legalize medical cannabis the night before, saying their vote will hurt suffering children. He’s also upset that lawmakers advanced a Republican-backed bill to reinstate the winner-take-all system in presidential elections.

Chambers spent much of the day Tuesday reading news articles aloud on the legislative floor, talking about Medicaid expansion and describing what it was like to get a colonoscopy.

The 78-year-old says he’s not going to relent on Wednesday or for the rest of the session. Lawmakers have less than five working days left before the session ends.
