(CNN) - Illinois Rep. Rahm Emanuel, a former Clinton administration aide, has accepted the position of President-elect Obama's chief of staff, a Democratic aide tells CNN.
House Minority Leader John Boehner criticized the choice of Emanuel - the man known for his tough-minded approach and widely credited with engineering large congressional gains for Democrats in the 2006 elections.
“This is an ironic choice for a President-elect who has promised to change Washington, make politics more civil, and govern from the center," Boehner said in a statement.
Meanwhile, Jim Manley, a senior communications advisor to Senate Majority Leader Harry Reid, praised the choice.
"An excellent choice. Rahm knows the Hill," he told CNN. "And he knows the White House. He is a brilliant strategic thinker and someone who knows how to get things done."
