Karen Handel is set to be sworn in after her victory in Georgia's 6th Congressional District.
Handel's swearing-in ceremony is planned for Monday evening at the U.S. Capitol. Handel is the first female Republican to be elected to a congressional seat in Georgia.
She defeated Democrat Jon Ossoff last Tuesday in the most expensive congressional election in history, with spending expected to top $50 million. Handel, a former Georgia secretary of state, ultimately won about 52 percent of the vote according to unofficial returns in the historically conservative district.
