The chances of the Republicans winning the House in the U.S. midterms are increasingly slim, according to the polls. They may even lose the Senate, as Democrats continue to gain ground.

Washington correspondents Katie Simpson, Willy Lowry and Paul Hunter take a look at where the midterm races are heating up, what's at stake for Republicans and Democrats, and just how worried Trump might be.

He also rejected international calls for oversight of AI, as he prepares to host Chinese President Xi Jinping.
