LINCOLN, Neb. (AP) — A leading abortion opponent is accusing state officials of selectively enforcing a policy that forbids advocacy groups from picketing inside the Nebraska Capitol.

Nebraska Right to Life Executive Director Julie Schmit-Albin raised the issue Tuesday after seeing supporters of a Medicaid expansion bill standing in the Capitol with signs around their necks.

Schmit-Albin says she has been told her group isn’t allowed to carry signs inside the building. State rules allow demonstrations on public sidewalks outside the building and on the East, West and lower North Terraces.

The Capitol’s tourism supervisor says she was unaware that the Medicaid group of roughly 100 was demonstrating inside the building.

Nebraska Right to Life hosts several Capitol events annually, including a “Walk for Life” in January that draws around 5,000 people.
