Washington (CNN) – Arizona Sens. John McCain and Jon Kyl endorsed fellow Republican Jan Brewer Monday for her own four-year term as governor.
"There has been no stronger defender of the State of Arizona than Governor Jan Brewer," McCain said in a joint statement he released with Kyl. "From border security to health care to job creation, Governor Brewer has consistently stood up for our state."
Brewer succeeded Gov. Janet Napolitano in January 2009 when Napolitano resigned to become President Obama's Secretary of Homeland Security.
Brewer has been at the center of a firestorm over a controversial immigration law in the state of Arizona. The law, which orders immigrants to carry their alien registration documents at all times and requires police to question people if there is reason to suspect they're in the United States illegally, was signed by Brewer on April 23.
McCain specifically endorsed Brewer's actions on immigration, including her efforts to stand against a lawsuit filed by the federal government designed to nullify the law.
"Governor Brewer continues to lead the fight against the Obama Administration's frivolous lawsuit against Arizona's immigration law," McCain said. "Governor Brewer is clearly the right leader to guide Arizona through these challenging times, and I am proud to support her."
The immigration issue also found its way into Kyl's endorsement.
"On this issue, immigration and others, she has shown courage in fighting for the rights of Arizonans. I am pleased to support her candidacy for Governor of Arizona," Kyl said.
Brewer will face off against her Republican primary challengers on August 24. The winner will advance to the general election.
