Valerie Jarrett's RootsCamp Speech Interrupted By Climate Activist Brad Johnson

White House Senior Adviser Valerie Jarrett was heckled during a speech on Friday by an activist demanding that President Barack Obama do more to address climate change.

Jarrett was about two-thirds of the way into her speech at RootsCamp, a conference for grassroots organizers being held in Washington, D.C., when Brad Johnson, campaign manager of Forecast the Facts and former editor of ThinkProgress Green, stood up and interrupted her.

According to HuffPost's Amanda Terkel, who was in the audience, members of the crowd began clapping in what was perceived as an attempt to drown Johnson out. Other attendees reported that members of the crowd booed, and that Secret Service agents moved toward the center of the ballroom. Jarrett apparently waved them off and spoke briefly with Johnson following her speech.

The "march" may have paled compared to protests and marches at past climate change conferences at Durban or Copenhagen, but for the civil society activists it was a big step.
