Boston (CNN) - As President Obama was pumping up thousands at a rally for Massachusetts Governor Deval Patrick, hecklers interrupted his remarks.
A press pool producer inside the Hynes Convention Center said the protesters held up a banner that read "Keep the Promise" as they chanted.
Another sign read "Fight Global Aids."
The wider audience began to shout them down with "four more years" and "yes we can."
A few minutes later, the President answered the hecklers by pointing out that his administration had increased funding for AIDS research. He suggested it's more than Republicans would achieve.
Obama rolled out his standard stump speech where he railed on Republicans for driving the economy into the ground.
He often leaned into the microphone and raised his voice urging the audience to get engaged and make a difference on November 2nd.
Along the way the President nearly lost his voice, which grew increasingly hoarse as he spoke, his ending remarks barely audible.
