Good morning and welcome to the US politics live blog. My name is Tom Ambrose and I’ll be bringing you all the latest news lines over the next few hours. President Donald Trump is once again in the mood for litigation. This morning he has threatened to sue Grammys host Trevor Noah after a joke he made about Jeffrey Epstein on stage. Joking that this will be his last year as host, Noah quipped: Song of the Year - that is a Grammy that every artist wants almost as much as Trump wants Greenland, which makes sense because Epstein’s island is gone, he needs a new one to hang out with Bill Clinton.
