Apple will reinstate Parler on its App Store following its multi-month ban, according to a letter Apple has sent to Sen. Mike Lee and Rep. Ken Buck, which was made public this morning via a post on Congressman Buck’s Twitter. TechCrunch also obtained the letter from Apple directly to confirm. The lawmakers had earlier written to Apple on March 31, 2021 to ask for additional information about why the app, which is heavily favored by conservatives, had been removed from the App Store. Apple’s response explains how Parler violated its policies but said it [Apple] has engaged in extensive conversions with Parler’s team since the app’s removal. It also says Parler’s proposed updates to the app, its content and its moderation practices will allow it to be approved for reinstatement to the App Store immediately update its release.

On March 31, @SenMikeLee and I sent a letter demanding answers about why Apple removed Parler from the App Store.
