Missouri Democratic Senator Claire McCaskill on Sunday dismissed GOP criticisms over President Obama swapping five Afghan detainees for Sgt. Bowe Bergdahl, the lone remaining American prisoner of war in Afghanistan.

“If in fact this man’s life had been lost, and it came out that we had this opportunity and our commander in chief passed on it, the Republicans would be going crazy right now,” McCaskill said on “Fox News Sunday” of the Obama administration negotiating with the Taliban.

The Taliban handed Bergdahl over to U.S. special forces on Saturday after the Obama administration agreed to transfer five Afghan detainees from the prison in Guantanamo Bay, Cuba to Qatar.

“While Bowe was gone, he was never forgotten," President Obama said Saturday, joined by Bergdahl's parents in the Rose Garden. "The United States of America does not ever leave our men and women in uniform behind."

However, Republicans said that Obama was required by law to inform lawmakers of any Gitmo transfers. And they said that by negotiating with terrorists, Obama essentially put a larger target on American soldiers overseas.

“We saved an American life on foreign soil, the president and foreign policy gets criticized,” McCaskill said, mocking the Republican criticisms. “Are you seeing a theme here? It’s politics.”

“We saved this man’s life,” the Democrat added. “The commander in chief acted within his constitutional authority.”
