Donald Trump is threatening to sue the BBC for $1bn, accusing it of fabricating part of his January 6 speech in a Panorama documentary. The letter from his lawyers demands a full retraction, an apology - and a huge payout.
Meanwhile in Washington, a former jihadi commander who once had a US government bounty on his head, now Syria's new president, has been welcomed to the Oval Office. Mark and James report on the extraordinary meeting, what it means for US foreign policy, and how it plays into Trump's push to reshape the Middle East.
And as the US government shutdown drags past 41 days, a last-minute deal could finally see federal workers paid and food programmes saved, but the political fights over health care and spending are far from over.
