Washington (CNN) - After a weekend of campaigning for Sen. John McCain's re-election bid in Arizona, Sarah Palin expanded her 2010 efforts on Monday by endorsing three military veterans running for Congress, calling them "a new generation of heroes who are heeding their country's call for leadership in Washington."
All three are Republican House candidates hoping unseat vulnerable Democrats in November.
The candidates: Vaughn Ward, a former CIA officer and Marine running in Idaho's 1st District; Allen West, a retired Lt. Colonel who served in Iraq and Afghanistan, running in Florida's 22nd District; and Adam Kinzinger, a pilot who flew combat missions in Iraq and Afghanistan, running in Illinois' 11th District.
Ward has already picked up McCain's endorsement.
"I believe that these great veterans will fight for us in D.C. to uphold and defend our constitution as courageously in the halls of Congress as they did on the field of battle," Palin wrote on her Facebook page Monday. "I'm so honored to offer my support to these American heroes, and I hope you'll join me in helping them so that they can serve us all in Washington."
The former Alaska governor will campaign for all three Republicans at a later date, along with donating to their campaigns.
