McConnell to return to Senate after recovering from head injury.

Senate Republican leader Mitch McConnell is returning to work on Monday after almost six weeks of medical leave due to a fall and concussion. His return comes as Congress faces important policy matters, including raising the nation's debt ceiling and negotiating additional aid for the Ukraine war. Several other senators have been out for medical reasons, raising questions about how much the Senate will be able to achieve with a 51-49 split between the parties. McConnell's absence, along with those of other senators, has added to the Senate's lethargic pace in the first few months of the year.
