Republican leaders have tapped the highest-ranking woman in their party, Rep. Cathy McMorris Rodgers (R-Wash.), to deliver the GOP response to President Obama's State of the Union address.

McMorris Rodgers serves as House Republican Conference chairwoman — a member of House GOP leadership.

In naming McMorris Rodgers, House Speaker John Boehner's (R-Ohio) office noted her roots in an eastern Washington farming family and her three small children at home, including a 2-month-old.

“Cathy McMorris Rodgers is proof that with humility, hard work and dedication, you can overcome any obstacle – a story to which many Americans can relate,” Boehner said.

Sen. Mike Lee (R-Utah) is delivering the tea party response after McMorris Rodgers.
