Democrats celebrate retaining control of Senate as Republicans take stock

House control still undecided as Republicans lead and attention pivots to Florida, where Trump is expected to announce 2024 run

As the balance of power in the US House of Representatives remained unresolved on Sunday, Democrats are celebrating the projection that they won control of the Senate, marking a significant victory for Joe Biden as Republicans backed by his presidential predecessor Donald Trump underperformed in key battleground states.

While senior Democrats remained guarded Sunday about the chances of keeping control of both chambers of Congress, House speaker Nancy Pelosi hailed the party's performance in the midterms following months of projections indicating heavy losses.
