Brown, Warren get testy in 2nd debate for U.S. Senate seat Republican U.S. Sen. Scott Brown, left, shakes hands with his Democratic challenger Elizabeth Warren prior to debate sponsored by the Boston Herald at the University of Massachusetts in Lowell, Mass., Monday, Oct. 1, 2012. / AP Photo/Charles Krupa Republican U.S. Sen. Scott Brown and Democrat Elizabeth Warren jousted on everything from immigration reform and Afghanistan to jobs and the Supreme Court during their second televised debate. Brown began Monday's match-up by demanding Warren release her personnel records at Harvard University, even as he conceded she is "a qualified academic." Warren pressed Brown for more information on the clients he represented as a private attorney and said if elected to the Senate, Brown would help fellow Republicans block President Barack Obama's agenda. Asked about Afghanistan, Warren broke with Obama, saying U.S. troops should be pulled home ahead of his 2014 withdrawal date. Brown said he'd rely on the judgment of Obama and his generals. The two also split on immigration, with Warren saying she supported the so-called DREAM Act, which Brown opposes.
