A record number of women have been elected

US President Donald Trump is claiming a 'tremendous success' after his Republican party held onto their majority of the US Senate overnight.

But the midterm elections will also see the Democrats take control of the House of Representatives.

That would make it much harder for the president to push through his agenda.

Democrats will view House victories in states like Florida, Virginia, Pennsylvania and Minnesota as cause for optimism as they prepare to hold the president to account in the run-up to the 2020 presidential election.

The election had a record number of women elected to the House, and also saw a number of firsts.

Ilhan Omar of Minnesota and Rashida Tlaib of Michigan, who are both Democrats, will be the first Muslim women to serve in Congress.

Massachusetts has its first black congresswoman - with Ayanna Pressley winning the state's seventh district.

Nancy Pelosi leads the Democrats in the House.

She says it's time to end "division" and for all parties to work together.

"Thank you all for making the future better for all of America's children.

"God bless you, God bless America - thank you all very much".
