Apple vs FBI: Google, Microsoft, Facebook and Amazon plan briefs in support

Alphabet Inc's Google, Facebook Inc, Microsoft Corp and Twitter Inc will all file or sign on to amicus briefs in support of Apple Inc's fight against a magistrate's order, which requires it to help the U.S. Federal Bureau of Investigation break into a San Bernardino shooter's iPhone.

Sources familiar with the matter told Reuters that Google and Facebook would make filings.

Microsoft will file a friend-of-the-court brief as well, company President Brad Smith said in Congressional testimony Thursday.

Twitter also will sign a brief in support of Apple, Twitter said.

Amazon.com Inc said on Thursday it will support Apple Inc's fight against a magistrate's order, which requires it to help the U.S. Federal Bureau of Investigation break into a San Bernardino shooter's iPhone.

An Amazon spokesman said the company was still working on its "amicus options."

The online retailer joins Alphabet Inc's Google, Facebook Inc, Microsoft Corp and Twitter Inc in voicing support for Apple.
