Washington (CNN) - U.S. Rep. John Murtha rested in a hospital Monday after being admitted the previous night due to abdominal pains caused by a gallbladder issue, his spokesman said.
"He's currently resting and doing well," said Matt Mazonkey, spokesman for the Pennsylvania Democrat.
Murtha is chairman of the House appropriations subcommittee on defense, and a strong critic of President Barack Obama's recent decision to deploy an additional 30,000 U.S. troops to Afghanistan.
He was scheduled to chair a subcommittee hearing Tuesday addressed by Defense Secretary Robert Gates and Secretary of State Hillary Clinton. Due to Murtha's illness, the hearing has been canceled.
