Joe Biden will officially become, this Wednesday, the 46th President of the United States.

He will be invested, like his vice-president Kamala Harris, at the end of a ceremony placed under very high surveillance, and at the end of a busy day and programmed to the minute.

It's D-Day in the United States.

Wednesday at midday (late afternoon in France), Joe Biden will succeed Donald Trump to be officially invested to become the 46th president to settle in the White House.

He will be sworn in in the federal capital Washington, cordoned off by the National Guard because of security threats.

This will also be the case for Kamala Harris, the vice-president-elect.

The duo will spend much of this necessarily special day together.

A few guests, but no audience

It will all begin with a mass for Joe Biden and Kamala Harris at 8:45 am.

They will then go to the Capitol.

This is where they will take the oath, one after the other.

Several speeches are planned.

Singer Lady Gaga will perform the American national anthem.

There will be a few guests, but social distancing will be respected.

The chairs were set up several meters apart.

However, there will be no audience.

But thousands of small flags placed on the Mall in front of the Capitol to represent the Americans.

Joe Biden will deliver his inaugural address.

It will then be 12 noon in Washington, 6pm in France.

Installation at the White House in the afternoon

Now president and vice-president, Joe Biden and Kamala Harris will review the troops.

This tradition symbolizes the peaceful transition of power.

They will join Arlington Cemetery in Virginia, just outside Washington, for a ceremony with former Presidents Obama, Bush and Clinton.

Finally, Joe Biden and Kamala Harris will be escorted to the White House in the afternoon, mid-evening in France.

Coronavirus and security oblige, there will be no official parade on Pennsylvania Avenue, as is the tradition.

And the 46th President of the United States will take possession of the Oval Office and will then sign his first decrees.
