CNN) - Former Secretary of State Condoleeza Rice Tuesday threw her support behind Carly Fiorina's U.S Senate bid.
In endorsing Fiorina Rice said in a statement, "California needs a representative in the U.S. Senate who is prepared to make the tough decisions necessary to address our most pressing challenges, including job creation and national security. Based on my personal experience, I know Carly is the best person to send to Washington to advocate for the people of our great state in the Senate."
Fiorina has previously worked with Rice and said in a statement, "I had the privilege to work with Secretary Rice when I served on the State Department's Advisory Committee on Transformational Diplomacy, and I have great respect for her. I am even more honored to have her support behind my campaign for U.S. Senate."
Fiorina, best known for her role as the former Chairman and Chief Executive Officer of Hewlett-Packard, is battling California State Assembleyman Chuck DeVore for the California GOP Senate nomination as well as former Rep. Tom Campbell. The latest polls suggest incumbent Democratic Sen. Barbara Boxer may face the toughest re-election fight she's had in recent years.
