US Republican Mitch McConnell news briefing

The presumptive Republican leader of the US Senate is holding a news briefing after the Republicans swept to victory in the Senate.

Senate Minority Leader Mitch McConnell earlier vowed to "work together" with President Barack Obama on issues where they can agree.

Mr McConnell said working within a two-party political system did not mean "we have to live in perpetual conflict".
