PHILADELPHIA -- A large group of Bernie Sanders' supporters occupied one of three media tents here for more than an hour as the Democratic National Convention was under way in the Wells Fargo Center.

Philadelphia police officers blocked the entrances to the media tent and refused to allow reporters inside to their work space or to report on the protest.

About 70 Sanders protesters, including several from Georgia, entered the tent quietly but quickly and refuse to speak to reporters. Many are wearing tape over their mouths.

The protest came just moments after Sanders led the effort to nominate Hillary Clinton for president.

Clarkston Mayor Ted Terry, a Sanders delegate, was not part of the protest. Terry said those that were will hopefully realize "now is not the time to fracture our larger progressive movement."

"I love my Bernie delegates," he said. "Luckily we don't live in a banana republic and won't be stuck with any president for more than eight years. Patience and longevity are a virtue in politics. Our progressives in Georgia need to have the long ball in mind."

One Georgia delegate who was inside the tent protesting, however, said they were "heartbroken" when Sanders asked that the convention nominate Clinton by voice vote.

"We were devastated," she said. "There was no way we could sit through any more speeches. We are angry. We are doing this on our own free will, individually and collectively."
