Lawmakers in the US have sent letters to Apple CEO Tim Cook and Larry Page, CEO of Google's parent company Alphabet, demanding information on how they collect and use personal information of users. Members of the Energy and Commerce Committee of the US House of Representatives sent the letters on Monday.

With recent media reports raising concerns about misuse of user data, the lawmakers sought information from the two companies on third-party access to consumer data, collection and use of audio recording data as well as location information via iPhone and Android devices.
