A closely watched hearing on net neutrality was temporarily halted for security reasons.
The Federal Communications Commission was debating whether to repeal rules that bar internet service providers from sorting users or businesses into tiers when Commissionr Ajit Pai abruptly called for a recess.
“On advice of security, we need to take a brief recess,” Mr Pai said.
The room was evacuated, and security officers could be seen patrolling the room with a dog.
Commissioners and audience members filed back in a few minutes later.
“We can now reconvene,” Mr Pai said.
