Summary
People across the US are casting votes in the midterm elections to determine who controls Congress
For two years, both chambers - the House of Representatives and the Senate - have been controlled by Democrats
The Republicans are predicted to take the House while Senate control is on a knife-edge and too close to call
Losing either chamber would hinder the agenda of Democratic President Joe Biden
There are also state-level elections and ballot measures which could mean new abortion laws in some states
Meanwhile Donald Trump hinted he may announce next week that he is running for president again in 2024
We’ll start getting results after polls close in the US this evening - that'll be the early hours of the morning, UK time
