Vice President Joe Biden was encouraged to run for president by first responders at a 9/11 memorial event aboard the Intrepid Museum in New York on Friday.

Firefighters, cops and other first responders greeted Biden with shouts of “Run, Joe, run!” the NY Post reports.

The vice president didn’t respond to his supporters, but it was the second occurrence in a week he encountered calls to run. He was met with similar chants when he marched in Pittsburgh’s Labor Day Parade.

On the Intrepid, the vice president spoke to a crowd of about 400 first responders and their families.

“Thank you for showing the United States and the world . . . courage,” he said.

“Courage isn’t that instantaneous reaction. Real courage is when you know what you are about to do, you had time to think about it, you know what the consequences is and you still do it. That’s courage.”

“They say time heals. I am not so sure that time heals. Maybe time dulls but it doesn’t heal,” he said.

Biden has been considering for weeks whether to enter the presidential race, and although he is undecided, his popularity is growing. 

A CNN/ORC poll released on Friday showed Biden 6 points ahead than he was last month.
