A few bullet points from an article:
President Biden has been in Ukraine and Poland this week. Biden called Jennifer McClellan from Poland to congratulate her on her winning a seat in the House.
She will be sworn in to the U.S. House at some point after the Virginia election results are certified.
McClellan informed the Virginia State Senate President Pro Tempore that she will resign her state senate seat by March 7, when the election results are expected to be certified, or when she is sworn in as a member of the 118th Congress, whichever happens first.
Virginia Democrats now focus on the race to fill her seat in the Virginia State Senate. The date of the special election has not yet been set.
Whoever wins the special election could have to defend the seat in a second party primary later this spring in the new 14th Senate District, which the Virginia Supreme Court created in political redistricting last year. About 80% of the new district lies in Richmond, with the remainder in Henrico County, which has a larger share of the current 9th District.

EDIT later to UPDATE:
The "firehouse primary" to fill her State Senate seat will be held Sunday Feb. 26.
The special election will be held Tuesday March 28.
