The race for both House of Representatives and Senate was a close run one between the Democrats and President Donald Trump’s party the Republicans.
Midterm elections take place halfway through a President’s term, and give the US the chance to reveal their feelings about Trump for the first time since his election in 2016.
There were 435 seats up for election in the House of Representatives and 33 out of 100 seats up for the vote in the Senate.
Both the House and Senate are in charge of passing through new laws, known as bills.

A total of 51 of those are Republican, 42 are Democrat and two belong to other parties.
There are five seats still left undeclared, however the Republicans have clinched the majority.
