Republicans have secured the 218 seats needed to win a majority in the lower chamber of the US Congress, the BBC’s US partner CBS News projects.
The party’s majority in the House of Representatives is razor-thin, but it is enough to stall President Joe Biden’s agenda for the next two years.
It marks a return to divided government, with Democrats still retaining power in the Senate.
Meanwhile, former President Donald Trump has announced he will run again.
Split control of Washington was ushered in by last week’s midterm elections, in which the Republicans – who had hoped to win back control of both chambers – underperformed expectations.
