Plans to feature Henry Kissinger at two Senate hearings Tuesday are off for now, because the former secretary of state is recovering from a broken shoulder.

With Republicans newly in charge of the Senate's committees, two chairmen had asked Kissinger to testify about national security strategy and American leadership in the world. Both the Armed Services and Foreign Relations panels say they will reschedule his appearance.

Kissinger said through his secretary in New York that he's recovering at home after breaking his right shoulder in late December and being hospitalized five days. He expects to be able to testify in late January.

Kissinger was secretary of state under Presidents Richard Nixon and Gerald Ford. He was awarded the Nobel Prize for negotiating American military withdrawal from Vietnam. He's 91.
