Republicans have secured the 218 seats needed for a majority in the lower chamber of Congress a week after the midterm elections, reports BBC.
The matter was projected by BBC's US partner CBS News.
While the party's margin in the House of Representatives is slightly ahed of their competitor, it is enough to stall President Joe Biden's agenda for the next two years.
But Democrats will keep control of the Senate when the new Congress convenes in January.
A handful of seats remain to be called.
The Republicans had hoped to win back control of both chambers, but they underperformed in comparison to their expectations in last week's midterms.
However, they won the seat they needed for their House majority on Wednesday when California's 27th district went to incumbent Mike Garcia.
According to CBS, the Republican party is now projected to win between 218-223 seats in the 435-seat House, But with votes in cliff-hanger races still being tallied, their majority may not be clear for days or even weeks.
