Fox News host Chris Wallace told Sen. Lindsey Graham (R-SC) on Sunday that he wished that he could put him on the "psychiatrist couch" to find out why the 59-year-old bachelor had never been married. Last week, a Washington Post profile of the South Carolina Republican noted that Graham had helped raise his sister after his parents died while he was in college. "Some of your friends suggested that might be the reason you never got married," Wallace observed during an interview on Fox News Sunday.
