GOP vice presidential candidate Paul Ryan's address at the Value Voters Summit in Washington D.C. Friday was marked with several audible interruptions, as protesters rose at various points to heckle the Republican congressman. In the clip above, a man can be heard cutting off Ryan, yelling "corporations aren't people," a reference to presidential candidate Mitt Romney's famous refrain. The audience quickly shouts him down with chants of "U-S-A, U-S-A," before he is hauled away by security personnel.
