WASHINGTON--Presumptive Democratic nominee Sen. Barack Obama (D-Ill.) is speaking now to AIPAC--the American Israel Public Affairs Committee conference. His speech is puncuated with applause and standing ovations. Sen. Hillary Rodham Clinton (D-N.Y) speaks next. GOP rival Sen. John McCain (R-Az.) spoke earlier.
"We will also use all elements of American power to pressure Iran. I will do everything in my power to prevent Iran from obtaining a nuclear weapon. Everything in my power. Everything," Obama said, departing from his prepared text to add the two everythings for emphasis.
