A senior adviser to Biden says the President-elect will likely make small tweaks to the inaugural address until the very end.

Biden has been working on this speech for weeks with his team, including with his speech writer Vinay Reddy and senior adviser Mike Donilon, who has played a major role in crafting so much of Bidens messaging over the years. 

Biden is known to be a meticulous preparer for speeches big and small and has been known to make changes up until the last minute. We’ve also heard the President-elect talk about how he marks up his speeches to help with pacing. 

Sen. Chris Coons, one of Bidens closest allies on Capitol Hill, told CNN he expects the speech to be one of optimism that notes the challenges the country has overcome together and also challenges "Congress to come together in partnership with him and meet the real needs of the American people."
