James A. Baker, III, former U.S. secretary of state and honorary chair of the Baker Institute, has joined President Barack Obama and Vice President Joseph Biden, as well as current and former officials from both sides of the aisle, to push for Senate ratification of the New START treaty before the year is over.

The president stressed the importance of bipartisan support for the arms reduction treaty, which he called "a national security imperative."

Additionally, Baker joined four other former secretaries of state -- Henry A. Kissinger, George P. Schultz, Lawrence S. Eagleburger and Colin L. Powell -- in writing a Dec. 2 Washington Post op-ed that encourages the Senate to put aside partisan differences and ratify the treaty.
