According to a report from Reuters, U.S. lawmakers who are probing Apple for alleged anti-competitive behavior have sought information from Spotify, the popular music streaming company, which has in the past accused Apple of anti-competitive behavior. Reuters reports the U.S. House of Representatives Judiciary Committee reached out to Spotify with requests for information, and also narrowed its requests with follow-up calls. Spotify and other developers have accused Apple of imposing rules that impede distribution on its App Store, the only path for app developers to reach more than 900 million iPhone users. Spotify’s previous complaint alleged Apple “makes it harder and harder for companies” to offer rival streaming services “all for the sake of tilting the field to favor its own services and disadvantaging those it is playing against”.

Spotify’s complaint was filed in the EU, a region known for its several anti-trust fights with top U.S. tech giants. The music streaming company has been pushing for antitrust action against Apple for several years. According to Reuters, Spotify representatives have met with officials of the U.S. Department of Justice, and also members of the FTC’s Technology Task Force, a group of 17 attorneys set up early this year to focus on internet competition issues. Reuters reports U.S. lawmakers have also tapped other companies for details on other tech giants.

The U.S. Department of Justice is also investigating Google, Facebook and Apple for anti-competitive behavior while the FTC is probing Amazon and Facebook, which is fresh off a $5 billion fine for privacy violations. In addition to the aforementioned probes, Amazon, Apple, Google and Facebook also face a surfeit of other antitrust investigations from both local (U.S.) and foreign regulatory bodies.
