Doug Jones will enter the Senate on Wednesday as the Democrat who did the impossible - he won his seat in Republican-dominated Alabama.
The arrival of Smith and Jones on Capitol Hill highlighted the extent to which the #MeToo movement has swept over Washington. Hatch's move opens the door to a potential run by Mitt Romney, the Republican's unsuccessful 2012 presidential nominee and one of the party's top critics of Trump. In 1964, Mondale was appointed to the United States Senate to fill the vacancy created when Hubert Humphrey was elected vice president.
Ninety-six percent of Black voters backed Jones, while Moore saw decreased turnout in more conservative voting blocs and areas.
Prior to Jones's swearing in Sewell was the lone Democrat in Alabama's congressional delegation.
After the swearing-in ceremony, dozens of Jones's guests headed to a hearing room in the Russell Senate Office Building, around the corner from the new senator's office.
Biden will speak afterward to a gathering of Jones' friends and family, a person familiar with his plans said.
The balance of power in the Senate will change from 52 Republicans and 48 Democrats-to 51 Republicans and 49 Democrats. Rep. Terri Sewell, who campaigned with Jones across the state, is the other Democrat.
He previously served as Legislative Director to Senator John D. Rockefeller IV of West Virginia.
Jones also chatted with Senate Majority Leader Mitch McConnell of Kentucky.
"Fake news will tell you we don't care for Jews", Kayla Moore said at a rally for her husband in rural Alabama on December 11.
The Alabama Secretary of State recently certified Jones as the election's victor after Moore refused to concede.
Alabama Senator-elect Doug Jones has picked a Black ex-Obama official to be his chief of staff.
Environmental issues did not come up very much during the special Senate election in Alabama, a race dominated by allegations against Republican candidate Roy Moore that he pursued inappropriate relationships with minors as an adult.
The decision was likely an easy one for Jones, having been a close friend of Biden's for more than four decades, with Jones once working alongside Biden as a young staffer on the Senate Judiciary Committee.
