Biden crossed the 270-vote threshold in the Electoral College on Saturday, at 11:25 am (E.T.) after the AP called Pennsylvania for him.

He was also able to capture Wisconsin, Michigan and Arizona, states that Trump carried in 2016.

The Trump campaign has filed multiple lawsuits to contest the legitimacy of certain ballots. The fate of those challenges is diminished after Biden was projected to have won the Electoral College.

Biden now holds the record for the most number of votes–over 73 million– cast for any presidential candidate in history, shattering the previous mark (69,500,000) set by Barack Obama in 2008.

Right now, he leads Trump by 4 million votes nationwide, and the number is expected to grow to 5 million and beyond.

The former vice president, who turns 78 this month, will become the oldest president in the history of the U.S.–it is his third attempt, after failures in 1988 and in 2008.

His running mate, Senator Kamala Harris, is the first Black woman and first Asian American elected vice president in U.S. history.

Trump, however, is not likely to concede defeat quickly. In a Wednesday tweet, the president declared without any proof or evidence that he had won in Pennsylvania, Georgia and North Carolina.

On Thursday, as it became clear that his early lead in Pennsylvania and Georgia was eroding as more ballots were tabulated, Trump posted a dramatic but silly tweet: “STOP THE COUNT!”

Trump flailed at the media, pollsters, election officials, mail-in voting, judges and Democrat-led U.S. cities Thursday evening, as his rival Joe Biden continued to inch toward a win in the 2020 election.

The president portrayed the counting of legally cast mail-in ballots as improper — an assault on American democracy by the president himself.

Biden’s election was as much about rallying support among Democrats, independents and even some Republicans with messages of unity and healing. It was a repudiation of Trump, whose approval rating never hit 50 percent.

In poll after poll leading up to Election Day, voters disapproved of Trump’s handling of the coronavirus pandemic, which has killed more than 235,000 Americans and infected close to 10 million in the U.S., including him and other top officials. such as his chief of staff.

Rather stupidly, Trump downplayed the virus, mocking Biden for wearing a mask and falsely claiming that we are “rounding the corner” on the pandemic at a time when cases and deaths from COVID-19 continue to rise.

After recovering from his own bout with the disease caused by exposure to the coronavirus — which led to a three-day hospitalization and forced the cancellation of one presidential debate — the president returned to the campaign trail in mid-October, holding rallies where he and many of his supporters eschewed the recommendations from public health officials to wear face masks and follow social distancing guidelines

The Biden campaign offered a sharp contrast, adhering to guidelines from Trump’s own Centers for Disease Control and Prevention, avoiding large rallies and making attendees at campaign events wear masks and follow social distancing guidelines.

Biden overcame numerous attacks from Trump on the campaign trail, including claims of cognitive lapses (Trump branded him “Sleepy Joe”) and questions about his son Hunter’s business dealings in Ukraine and China. Trump even called on Attorney General William Barr to launch an investigation into the Bidens just two weeks before Election Day. (Barr did not.)

He also floated wild conspiracy theories and disinformation about Biden and other Democratic figures that had been promoted by right-wing activists on social media.

“If I lose, I will have lost to the worst candidate, the worst candidate in the history of presidential politics,” Trump said at an Oct. 17 campaign rally.

The president also accused Democrats of trying to “steal” the election, falsely claiming that mail-in voting would lead to widespread fraud.

The pandemic caused many states to expand early-voting options, and a record 101 million ballots were cast either in person or by mail before Election Day.

In 2016, Trump won office by riding a populist message against a deeply unpopular establishment candidate in Clinton. But polls showed Biden as far more popular with the electorate than the former secretary of estate, giving him more ways to win the election.

Biden, a Scranton, Pa., native, began his presidential campaign in April 2019, joining an already crowded field of Democrats with a video denouncing Trump for his response to the violent white-supremacist rally in Charlottesville, Va., in August 2017. While speaking out against the violent clashes that erupted among white supremacists and counter-protesters, Trump infamously said there were “some very fine people on both sides.”

“With those words, the president of the United States assigned a moral equivalence between those spreading hate and those with the courage to stand against it,” Biden said in the video. “And in that moment, I knew the threat to this nation was unlike any I had ever seen in my lifetime.”

He carried that message into the general election campaign, promising that his election would “restore the soul of the nation.”

Biden shrugged off disappointing performances in early primary and caucus states like Iowa, New Hampshire and Nevada, gaining his footing after a crucial win in South Carolina, where he was buoyed by the support of African American voters wary of the candidacy of Sen. Bernie Sanders, I-Vt., who had emerged as the frontrunner. Biden went on to control of the race,  winning 10 of 14 states on Super Tuesday in March. Sanders dropped out of the race and quickly endorsed Biden, paving the way for his nomination.

While Biden enjoyed a wave of support among Democrats, he was also backed by “Never Trump” Republicans who opposed the president from the start of his term or became disillusioned by what they considered to be his chaotic and divisive style of governing. During the campaign, Biden was endorsed by dozens of Republican former national security officials, U.S. attorneys and governors, including former Ohio Republican Gov. John Kasich, former Michigan Republican Gov. Rick Snyder, former Arizona Republican Sen. Jeff Flake and Cindy McCain, the widow of the 2008 Republican nominee for president, Sen. John McCain of Arizona.

Biden now faces the enormous challenge of attempting to unify a country deeply divided by partisan politics. While that reality predated Trump’s time in office, it also crystallized over the last four years.

Joseph Robinette Biden Jr. was born in Scranton, Pa., on Nov. 20, 1942, to Catherine Eugenia “Jean” Biden (née Finnegan) and Joseph Robinette Biden Sr. He was raised in Scranton and New Castle County, Del.

Biden studied at the University of Delaware before earning his law degree from Syracuse University in 1968.

He married his first wife, Neilia Hunter, in 1966. They had three children: Joseph R. “Beau” Biden III (born 1969), Robert “Hunter” Biden (1970) and Naomi Christina Biden (1971). A month after he won his first race for the U.S. Senate in 1972, Neilia and Naomi died in a car accident that also injured his sons.

During his six terms in the Senate, Biden commuted by train between his Delaware home and Washington, D.C. — 90 minutes each way.

He met his second wife, Jill, in 1975, and they married in 1977, having a daughter, Ashley,  in 1981.

Biden mounted two unsuccessful presidential bids, in 1988 (which was marred by a plagiarism scandal) and 2008 (which he lost to Barack Obama, who ultimately picked him as his running mate).

He flirted with the idea of running again in 2016 but was too grief-stricken over the loss of his son Beau, who died of brain cancer in 2015 at the age of 46.

“Beau should be the one running for president, not me,” he told MSNBC host Joe Scarborough in January. “Every morning I get up, Joe, not a joke, and I think to myself, ‘Is he proud of me?’”
