Republicans are calling on the Federal Election Commission (FEC) to probe the alleged censorship of Conservatives by Google’s email platform, Gmail, after a study showed it allows the vast majority of emails from Left-wing politicians to land in a user’s inbox while more than two-thirds of messages from Conservative candidates are marked as spam. The Republican National Committee (RNC), National Republican Congressional Committee (NRCC), and National Republican Senate Committee (NRSC) have filed a joint complaint with the Federal Election Commission to investigate the arguments made in a new study by North Carolina State University that Gmail suppresses Conservative candidates’ emails at a much higher rate than Liberal ones.

RNC Chairwoman Ronna McDaniel, NRSC Chairman Sen. Rick Scott, and NRCC Chairman Rep. Tom Emmer issued a joint statement accusing Big Tech of unfairly shaping the political playing field. “As midterm elections approach, we are formally calling on the FEC to investigate the extent and intentionality of Google’s censorship of Republican fundraising efforts,” read the statement provided to Fox News Digital. “This is a financially devastating example of Silicon Valley tech companies unfairly shaping the political playing field to benefit their preferred far-left candidates. "Companies like Google don’t think you have the right to hear both sides: they’d rather make the decision for you," it read.

Google has dismissed the University study’s findings. “Political affiliation has absolutely no bearing on mail classifications in Gmail and we’ve debunked this suggestion, which has surfaced periodically from across the political spectrum, for many years,” a Google spokesperson previously told Fox News Digital after the study’s release. “Mail classifications in Gmail automatically adjust to match Gmail users’ preferences and actions. Gmail users can move messages to spam, or to any other category,” the Google spokesperson added. “Gmail automatically adjusts the classifications of particular emails according to these user actions.” Conservative candidates raised $737 million on the Republican fundraising platform WinRed from Gmail users in 2019 and 2020. Because, according to the study, just 32% of fundraising emails were delivered, the Republicans estimate they missed out on $1.5 billion in contributions during the 2020 election cycle.

The GOP committees assess that their candidates have missed out on $529 million in donations due to Gmail's filtering algorithms.
