Protesters at the Denver airport over the weekend were told by police that it was illegal to exercise “free speech without a permit.”

Denverite reported that over 200 people gathered at the Denver International Airport on Friday to protest President Donald Trump’s executive order banning travel from seven majority-Muslim countries.

In video posted to YouTube, Police Commander Tony Lopez can be seen advising demonstrators that they are in violation of the law.

“Stop doing anything that could be construed as free speech without a permit,” he explains.

Lopez warns in the video, which lacks context, that even carrying a copy of the U.S. Constitution was prohibited in the airport.

“I cannot carry the Constitution without a permit?” one protester asks.

“Correct,” the officer replies.
