Apple has again declined a request to testify at a congressional hearing scheduled for March, focused on the technology industry’s relationship with China. This is the second such hearing that Apple has declined to attend since November.

The Washington Post reports that Republican Senator Josh Hawley invited both Apple and TikTok to appear at a hearing scheduled for March 4. Both companies have denied to attend, though TikTok said it would “dispatch a top aide to appear at an unspecified later date.” Apple made no such comment.

Both Apple and TIkTok skipped a similar hearing last November, and faced quite a bit of criticism from Hawley for doing so. The senator accused TikTok of representing the “danger of Chinese tech platforms’ entry into the U.S. market” and Apple of representing “the danger of American tech companies’ operations in China.”

Hawley also criticized Apple for storing iCloud data of Chinese users on a government-owned server, which it is required to do by law. The Washington Post explains:

Despite the fact that neither Apple nor TikTok will attend the March 4 hearing, Hawley sill plans to hold it, today’s report says. U.S. law enforcement officials are set to testify, Hawley’s office pointed out.

Apple’s relationship with China has drawn concern from lawmakers on both sides of the aisle. Back in October, the likes of Alexandria Ocasio-Cortez and Ted Cruz penned an open letter to Tim Cook on the matter, questioning some of Apple’s decisions regarding the App Store in China and potential censorship.
