The Associated Press reports the baby, which weighs 8 pounds and 4 ounces, was born in Washington. 

Cotton said last week that he would likely miss some of the debate this week on a bill to let lawmakers weigh in on a final Iran nuclear deal. The senator, who is offering changes to the Iran legislation, said he would not let his son "live under the threat of a nuclear Iran."
