CNN) — Sen. Robert Byrd, the longest-serving senator in American history, announced Monday he is endorsing Barack Obama's White House bid.
Byrd, 90, has served as West Virginia's senator for nearly fifty years, and is one of the chamber's most vocal critics on the war in Iraq.
"After a great deal of thought, consideration and prayer over the situation in Iraq, I have decided that, as a superdelegate to the Democratic National Convention, I will cast my vote for Senator Barack Obama for President," Byrd said in a statement released by his office. "Both Senators Clinton and Obama are extraordinary individuals, whose integrity, honor, love for this country and strong belief in our Constitution I deeply respect."
