Video has surfaced of TSA agents conducting security tests on beverages bought inside of US airports, two months after RT first reported that passengers were being subjected to added drink screenings at a Colorado airport.

RT was quick to report in July that agents with the Transportation Security Administration were routinely testing store-bought beverages purchased inside of the airport for explosive chemicals, according to an investigation first carried out by Grand Junction, Colorado’s KJCT-8 News. Only a few weeks later, an irritated airline passenger preparing to board witnessed a similar screening first-hand was able to document it.

In a video uploaded to YouTube over the weekend, user Dan Holland writes, “While waiting in the Columbus, OH airport for our flight to Oakland, I couldn’t help but notice the two TSA women that were ‘testing’ any and all liquids that people had in their hands.”
