Rep. Jim Jordan, R-Ohio, delivered a letter to Microsoft president Brad Smith on Monday, alleging that although it’s mostly escaped the notice of House Democrats, the business is one of the Big Tech firms”out for conservatives.”

Jordan notes that Democrats’ investigations into the use of Big Tech have mostly overlooked Microsoft, despite its own size and other seeing reports regarding its own operations.

“Regardless of Microsoft’s size and market dominance, House Democrats strangely failed to significantly analyze Microsoft’s behavior during their evaluation of rivalry from digital markets,” the letter reads. “Democrats also appear to have excluded Microsoft from scrutiny in their big bundle of bills to dramatically rewrite American antitrust law.”

Jordan also points out that Microsoft has gained over 200 companies throughout the previous ten years and has a market cap next only to that of Apple one of U.S. businesses.

In his correspondence, Jordan declared a recent example where folks using Microsoft’s search engine Bing were not able to pull up pictures of the Tiananmen Square tank guy around the anniversary of their protests. Microsoft attributed the absence of search results to”unintentional human mistake “

In addition, he calls into question Microsoft’s editorial management in its own user-generated content inside its own Word app, and censorship of particular topics on its own LinkedIn platform.

Jordan asked responses to a number of queries from Smith”immediately.”

A spokesperson for Microsoft didn’t return FOX Company’ petition for comment on the letter.

Lately, a bipartisan group of House lawmakers introduced numerous antitrust measures, such as one built to possibly break up big tech firms operating companies with conflicts of interest.

The proposals, generally speaking, are thought to be aimed at Google, Apple, Facebook and Amazon, impacting companies just with a $600 billion market value and 500,000 or monthly active consumers.

There are many ongoing efforts in courtroom involving these businesses to attempt and make certain they don’t participate in monopolistic behaviours.
