Sen. Lindsey Graham said that his friend and colleague Sen. John McCain will return to Capitol Hill sometime this month.
"Sen. McCain is in rehab. He's coming back in January," Graham said Sunday on CBS' "Face the Nation." "We need his voice now more than ever."
McCain was hospitalized in December for side effects related to his ongoing treatments for glioblastoma, an aggressive form of brain cancer.
McCain later tweeted that he would return after the holidays.
