Former Vice President Joe Biden on Thursday announced his decision to run for president for a third time, ONA reports citing CNN.
The announcement came in a campaign video released Thursday morning.
"The core values of this nation ... our standing in the world... our very democracy ... everything that has made America -- America -- is at stake. That's why today I'm announcing my candidacy for President of the United States," Biden tweeted, along with the campaign video.
Biden, 76, enters the crowded Democratic primary field of 20 candidates as the presumptive front-runner sitting atop the most recent polls. But his more than four-decades-long career is set to undergo an unprecedented level of scrutiny as he seeks to win the Democratic nomination to take on President Donald Trump in a general election.
This will mark Biden's third attempt for the White House after two failed bids in 1988 and 2008. His first presidential run was plagued by charges he plagiarized in law school and in campaign speeches. In 2008, he dropped out of the presidential contest after a poor showing in the Iowa caucuses, placing fifth with less than one percentage point.
Biden has described himself as an "Obama-Biden Democrat," a sign he would embrace the mantle of the Obama administration in a presidential campaign. The former vice president has led most early polls of potential Democratic contenders and has enjoyed high name identification and favorability ratings, which rose in the years since leaving public office.
Throughout his career in Washington, Biden has embraced a blue-collar, middle-class message, delved into foreign policy debates and talked about the need to engage in bipartisanship. On the campaign trail last fall, he cast the election as a "battle for America's soul," a theme that will be central to his presidential campaign.
Biden will be among the oldest candidates in the Democratic primary field, and he has acknowledged his age would be a "legitimate issue" for voters and opponents to raise.
