The stakes are high for Biden's inaugural address. Here's what to expect.

A transition official said that Biden has been working on the speech this weekend with family members and his senior adviser Mike Donilon and that the address will emphasize familiar themes from his campaign: unity, healing and a vision for the many crises the country faces.

As he unveiled his $1.9 trillion economic package last week, Biden said bipartisanship was essential to addressing the economy and the Covid-19 pandemic: "Unity is not some pie-in-the-sky dream — it's a practical step to getting the things we have to get done as a country get done together," he said.

The speech is "going to be Joe Biden," because "unity is part of who Joe Biden is.".

In an interview Sunday on ABC News' "This Week," incoming White House communications director Kate Bedingfield said the speech "will be a reflection of a lot of what you heard from him on the campaign trail, which is that he believes we can bring this country together."

"He believes that we have to bring this country together, that a unified America is the only way that we're going to be able to tackle the massive crises that we're grappling with," she said, adding:

"I think you can expect that this will be a moment where President-elect Biden will really work to try to turn the page on the divisiveness and the hatred over the last four years and really lay out a positive, optimistic vision for the country and lay out a way — lay out a path forward that really calls on all of us to work together."
