Joe Biden has officially become the Democratic presidential nominee after Democrats nominated him as their 2020 candidate on Tuesday night, August 18, the second day of the Democratic National Convention.

Following a roll call vote held virtually, Biden secured enough Democratic delegates and won the nomination, more than three decades after he first campaigned for the president of the United States.

“Thank you very, very much from the bottom of my heart,” Biden said from Delaware after the vote. “It means the world to me and my family.”

The former vice president also wrote in his tweet: “It is the honor of my life to accept the Democratic Party’s nomination for President of the United States of America.”

Due to the CCP Virus (coronavirus) pandemic, Democrats took the roll call of votes at the party’s national convention, which showcased videos of delegates in every state and territory declaring their support for Biden, according to The Hill.

Former President Barack Obama congratulated Biden on his formal nomination, saying that “I’m proud of you.” Biden served as Obama’s vice president for eight years.

“It is the honor of my life to accept the Democratic Party’s nomination for President of the United States of America,” Obama wrote in a tweet on Tuesday night.

Obama will speak on the third night of the virtual convention on Wednesday, and Biden will deliver his acceptance speech on Thursday at the conclusion of the four-day event.

The Democrats nominated Biden to take on President Donald Trump 77 days before the November election.

During a campaign stop in Yuma, Arizona, on Wednesday, President Trump told supporters that he has kept key promises to build a border wall, cut taxes, and protect Americans from foreign criminals and invaders. The president also used his speech to attack Biden and Democrats on immigration policy.

“Joe Biden is the puppet of a Radical Left wing movement that seeks the complete elimination of America’s borders and boundaries,” President Trump said. “They want to take the wall down. They don’t want to have borders. They want to have sanctuary cities.”

In his battleground campaign tour, President Trump will reportedly also visit Biden’s hometown, Scranton, Pennsylvania, on Thursday while Biden will be simultaneously delivering his virtual acceptance speech from his basement.
