According to a recently released campaign finance analysis, President Joe Biden raised enormous amounts of money in the last election from employees of well-known technology companies such as Facebook, Amazon, Microsoft, and Apple, surpassing even other corporate donors.

As reported by the Washington Examiner, Biden raised about $15 million from these companies’ employees, making them the five largest aggregate corporate donors to Biden’s campaign and joint fundraising committee.

While corporations are not allowed to contribute directly to fundraising campaigns, their employees can do so while denoting their political leanings.

According to Federal Election Commission, Google Alphabet employees donated about $5.3 million, Facebook staff gave the campaign about $1.9 million, while Amazon employees donated $2.6 million. Microsoft and Apple employees, meanwhile, donated $32 million and $1.9 million, respectively.

Dustin Horowitz, the co-founder of Facebook, donated $46 million to Biden’s campaign. Most of the amount donated went to Future Forward USA, a public cooperative research institute that reports to the Federal Election Commission as a Future Forward PAC.

Meanwhile, the funds donated by tech giants to Donald Trump’s campaign were comparatively minor, managing to raise about $500,000 total.

Former President Trump’s campaign was primarily funded by employees of American Airlines, Boeing, Bank of America, Lockheed Martin, and Wells Fargo, each donating less than $400,000, according to data from the nonpartisan Center for Responsive Politics.

During the Trump administration, tech companies waged an intense campaign to attack mainly conservative-minded personalities like President Trump. 

Likewise, former President Trump criticized the technology giants for dividing the country after they decided to suspend his account, after judging him guilty of instigating the riots on January 6 at the Capitol. That riot was largely infiltrated by leftist activists, ignoring that most of his followers on the day of verifying votes by Congress came from different parts of the country peacefully.

“I think that Big Tech is doing a horrible thing for our country and to our country, and I believe it’s going to be a catastrophic mistake for them. They’re dividing and divisive,” Trump said last month.

According to Fox Business, Democratic presidential candidates such as Hillary Clinton and Barack Obama similarly received significant contributions from tech company employees, and donation sources even extended beyond the tech sector.

According to data compiled by the Center for Responsive Politics, top funders for Clinton in the 2016 election campaign included employees of personal injury law firm Morgan & Morgan and JPMorgan Chase & Co., along with Google, Microsoft, and Apple.

Whereas four years earlier, Obama’s campaign was financially backed by corporate employees of primarily Microsoft and Google, though he also received funds from Deloitte, Time Warner (now part of AT&T Inc.), and law firm DLA Piper.

So far, GOP lawmakers have accused big tech companies of bias against them, including accusations directed at these companies that censor online content to favor liberal views.

As Fox Business points out, there is currently bipartisan support in Congress for an antitrust investigation against Google, Facebook, Amazon, and Twitter to reduce their influence.

Facebook CEO Mark Zuckerberg, Twitter’s Jack Dorsey, and Sundar Pichay of Google subsidiary Alphabet Inc. are expected to testify before a House panel next month.
