Texas Tribune update:

DPS officials confiscated one jar they suspected had urine and 18 jars they suspected had feces while searching bags of people entering the gallery, the department confirmed in a press release Friday afternoon.

Rumors had persisted earlier Friday that some protesters had tried to bring such containers into the gallery, but DPS officers outside the gallery said they had no knowledge of such attempts at the time.

The DPS issued a press release on what they’ve found so far:

AUSTIN - The Texas Department of Public Safety (DPS) today received information that individuals planned to use a variety of items or props to disrupt legislative proceedings at the Texas Capitol.

Therefore for safety purposes, DPS recommended to the Texas Senate that all bags be inspected prior to allowing individuals to enter the Senate gallery, which the Texas Senate authorized.

During these inspections, DPS officers have thus far discovered one jar suspected to contain urine, 18 jars suspected to contain feces, and three bottles suspected to contain paint. All of these items - as well as significant quantities of feminine hygiene products, glitter and confetti possessed by individuals - were required to be discarded; otherwise those individuals were denied entry into the gallery.

In the interest of the safety and security of Texas legislators and the general public, these inspections will continue until the conclusion of Senate business.

Not quite proof, but getting closer.
