President Biden says Donald Trump's impeachment trial "has to happen".

House impeachment managers deliver the article of impeachment against Donald Trump to the Senate, formally triggering a trial. Meanwhile, President Biden continues to reverse many of the executive orders from the Trump era while emphasising his message of unity. Oh, and Rudy Giuliani is being sued by the Dominion voting machine firm for $1.3bn (£950m).

Emily, Jon and Anthony are joined by Slate's Dahlia Lithwick.
