A growing list of tech companies have vowed to stand behind Apple in court as it asks a federal magistrate to reverse her order forcing the company to help the FBI hack an iPhone belonging to one of the San Bernardino shooters.

On Thursday, Apple filed the order, accusing the federal government of seeking "dangerous power" through the courts and of trampling on its constitutional rights.

"The government says: 'Just this once' and 'Just this phone.' But the government knows those statements are not true," read Apple's filing.

But Apple won't be alone in its battle – many tech companies have confirmed they will file "friend of the court" briefs in support of Apple's case.

Microsoft

During U.S. House Judiciary Committee Hearing Thursday, Microsoft president and chief legal officer Brad Smith declared Microsoft "wholeheartedly" supports Apple and said the company would be filing a brief to support the case.
