Washington — It's one week after Election Day 2024, and while control of the White House and the Senate have been decided, in a handful of races for the U.S. House of Representatives, the results are still outstanding, and their outcomes will determine Republicans' margins in the lower chamber.

Competitive House races remain undecided in Los Angeles, Orange, Riverside and San Bernardino counties. The Southern California contests could play roles in determining the balance of power in the US House of Representatives. Adding to the uncertainty, several California Republicans are representing districts that President Biden won in 2020.
