A US senator's health issues are keeping him from returning to work. The senator, who is 84 years old, has been in a hospital since mid-June. He is now in a rehab center, where he is undergoing therapy.

His office announced that he would not be back in the Senate this week. This means he will miss a major political event in his home state. Further information about the senator's condition is available from national news sources, including a report from The New York Times.
