Joe Biden has officially been sworn in as the forty-sixth President of the United States and, in the aftermath of his acceptance speech, everyone is saying the same thing.

Here's the full story...

It's a new era for the United States of America.

President Biden today took the oath of office, thus projecting at least 4 years under the rule of the Biden-Harris Administration.

But the suspense surrounding today has been building for months.

Since President Biden's election victory on November 7th, our country has experienced political tensions like never before.

Most people argue that Biden's win was a fair one...

Getty

After 4 long days of vote counting - and plenty of recounting - the Democrat was projected as the forty-sixth President of the United States.

However, people on the other side of the political spectrum didn't take his win so readily.

Getty

Trump instantly attacked Biden's win with several unproven accusations of electoral fraud - and, of course, his loyal supporters added fuel to the flames with gusto.

Trump did everything in his power to fight the election result...

And 2 weeks ago on January 6th, enraged pro-Trumpers took matters into their own hands.

After repeated instructions by Trump to "fight for the White House," hundreds of his supporters stormed the U.S Capitol...

During which a joint session of Congress had convened to formally count the Electoral College votes and certify Biden's election win.

So, for today's inauguration ceremony...

Security was tighter than ever before.

Earlier this week, shocking photos from Washington D.C began to emerge...

Getty

And they demonstrated just how seriously the authorities were taking the event, and the measures in place to ensure there would be no repeat of the scenes from January 6th.

As we all know, Trump didn't attend the inauguration.

Getty

He confirmed his absence in a tweet earlier this month before being banned from Twitter.

Instead, Trump left Washington D.C on Air Force One this morning...

Getty

And headed for the Mar-A-Lago resort in Florida.

Trump is the first president in more than a century to not attend his successor's inauguration.

Getty

Only 3 presidents have have done the same, with the last, Andrew Johnson, coming in 1869.

But regardless of Trump's absence, the inauguration went ahead smoothly...

Getty

And the entire world watched on as President Biden and his vice president, Kamala Harris, made their way through this sacred ceremony.

Biden's swearing-in was an emotional moment for many Americans...

Getty

And it signalled a new era for our country.

And of course...

How can we not mention Lady Gaga's performance of the national anthem?!

But the moment everyone is talking about right now is President Biden's acceptance speech.

Getty

The new president gave a lengthy and emotional speech, where he addressed the deeply divided nation on what the next 4 years will hold under his ruling.

Biden promised to "write an American story of hope"...

Getty

As well as weighing in on the devastating effects of the coronavirus pandemic and the issue of racial inequality across the country.

"Millions of jobs have been lost. Hundreds of thousands of businesses closed. A cry for racial justice, some 400 years in the making, moves us. The dream of justice for all will be deferred no longer. A cry for survival comes from the planet itself, a cry that can't be any more desperate or any more clear now."

But there's one part of his speech that stands out among the rest...

Getty

And people cannot get enough of it.

​Yep, President Biden has become the first POTUS to ever challenge white supremacy in his inauguration speech. 

Getty

He said this:

"The rise of political extremism, white supremacy, domestic terrorism, that we must confront and we will defeat."

The president then added:

Getty

"To overcome these challenges, to restore the soul and secure the future of America, requires so much more than words. It requires the most elusive of all things in a democracy - unity."

Congratulations, President Joe Biden!
