US senators criticize Apple for not testifying on anti-trust concerns

Apple Inc is refusing to testify at an upcoming United States Senate subcommittee hearing on competition issues related to mobile app stores, the bipartisan leaders of the panel said on Friday.

App makers long have accused Apple's App Store for iPhones and iPads, along with Google's Play store for Android devices, of engaging in anti-competitive behavior by requiring certain revenue sharing payments and setting strict inclusion rules. A subcommittee hearing was being planned for late April but no date has been set yet.

Senators Amy Klobuchar, a Democrat, and Mike Lee, a Republican, said they wrote to Apple Chief Executive Tim Cook on Friday urging the company to reconsider. Apple did not immediately respond to a request for comment.

Apple and game maker Epic Games are scheduled to square off on those issues in a federal trial beginning May 3 in California. A spokeswoman for Klobuchar did not immediately comment on whether Google or other companies had agreed to testify at the planned subcommittee hearing.

Google has agreed to testify at the hearing, a source said. The company did not immediately respond to a request for comment.
