ABC News Jonathan Karl and Karen Travers report: Former Vice President Dick Cheney is at George Washington University Hospital in Washington tonight after experiencing chest pains.
Cheneys doctors are evaluating the situation and the former vice president is resting comfortably, his spokesman told ABC News tonight.
Cheney has a long history of heart problems. He has had four attacks, the first in 1978 when he was just 37 years old and the most recent in November 2000 after he and former President George W. Bush were elected to the White House. In 2001 Cheney had a pacemaker installed into his chest and last September he underwent elective back surgery to treat lumbar spinal stenosis.
On Friday Cheney is scheduled to see former President George W. Bush for the first time since they left office last January at a breakfast reunion of Bush White House staffers.
The news of Cheneys hospitalization first broke because his daughter, Liz Cheney, cancelled a scheduled appearance at the Lincoln Day Republican dinner in Schaumburg, IL tonight.
Liz Cheney was to be the keynote speaker at the fundraiser organized for the Republican committees of Barrington, Elk Grove, Hanover, Palatine, Schaumburg and Wheeling townships.
An Illinois Republican involved with the planning of the event tonight said that he spoke to an aide to Liz Cheney at about 11am ET today.
The aide informed this official that Liz Cheney would not be able to attend the event because she was in Washington and at the hospital with her father.
