The Texas Department of Public Safety says some protesters tried to carry what appears to be urine, feces and paint into the gallery as senators gather to vote again on new abortion restrictions.
DPS issued a statement Friday after troopers were seen seizing feminine hygiene products and other items from people entering the Capitol. The agency says the Texas Senate authorized all bags to be inspected for anyone entering the gallery.
It says troopers also found large numbers of glitter and confetti.
DPS plans to continue bag searches as long as the Senate is in session.
Lt. Gov. David Dewhurst -- the Senate president -- has tightened security and promised to stop disruptions after shouting protesters ran out the clock on a vote in the last session.
