House Speaker Nancy Pelosi (D-Calif.) was heckled during a speech she gave before a gathering of liberal activists Tuesday in Washington. 

A short YouTube video recording has emerged of the flap at the "America's Future Now" conference. Protesters unfurled at least three banners, one of which read "Stop Funding Israeli Terror," likely a reference to the Gaza flotilla controversy. 

At points, Pelosi can be heard raising her voice trying to speak over the protesters' shouts. During the video, rounds of applause for the Speaker can also be heard.
