I think you’ve hit the nail on the head. There needs to be some control over what is allowed, and either this group or their congress people or Kev screwed up.
Think about if the gay men’s choir. showed up unannounced and started singing anything at all- do you think there might be some complaints?
“Of course, because the singers in this situation were children, our officers were reasonable and allowed the children to finish their beautiful rendition of the Star-Spangled Banner,” the statement added. “The Congressional staff member who was accompanying the group knew the rules, yet lied to the officers multiple times about having permission from various offices. The staffer put both the choir and our officers, who were simply doing their jobs, in an awkward and embarrassing position.”
