Though Harris is leaving her Senate seat, she s not technically leaving the Senate behind entirely. Harris will be sworn in on Wednesday by Supreme Court Justice Sonia Sotomayor
As vice president she also holds the role of being president of the Senate. The title allows Harris to preside over the chamber and break 50-50 ties, effectively handing Democrats the majority for the first time since 2014 once she is sworn in on Wednesday.
Democrats failed to lock down the majority in November but squeaked out a 50-50 majority after winning the two Georgia runoff elections. This is not a goodbye for Vice President-elect Harris, said a Harris aide. As she resigns from the Senate, she s preparing to take an oath that will allow her to preside over it.
