Senate hopeful Elizabeth Warren's camp weighs in on Romney's VP pick

Updated:

Elizabeth Warren's campaign is criticizing Mitt Romney's Vice Presidential choice, Paul Ryan, as "ultra right-wing" and insisting that Scott Brown would "rubber stamp a radical and reckless
Romney-Ryan agenda." 

In an email, Warren's campaign manager, Mindy Myers, urged supporters to help Warren take on the "Romney-Ryan-Brown slate of Republicans in Massachusetts.  She said Republican control of the US Senate would "make that agenda unstoppable."

The Brown-Warren race is closely watched nationwide, since the outcome could tip the balance of the Senate.
