It's a boy for Rep. Cathy McMorris Rodgers, the first member of Congress to give birth in more than a decade, her office said Monday.

Cole McMorris Rodgers arrived a month early on Sunday at Bethesda Naval Hospital in Maryland. He weighed 5 pounds, 9 ounces and was in the Neonatal Intensive Care Unit to address minor complications.

"Although he arrived early, both the baby and I are doing well and recovering at the hospital," McMorris Rodgers said in a statement. "We look forward to soon being able to bring our son home."

Cole is the first child for the 37-year-old Republican, who is the fifth woman to give birth while serving in Congress, all in the House, according to research by her aides.

McMorris Rodgers learned she was pregnant while campaigning last summer for a second term. She chose not to reveal the pregnancy until after the election, which she won easily.
