Google deputy general counsel Mike Yang and public policy director Pablo Chavez are preparing to deliver a closed-door briefing on Thursday, says Ken Johnson, Mack's senior adviser. The audience will be restricted to members of the House Subcommittee on Commerce, Manufacturing and Trade, which Mack chairs. Rep. G.K. Butterfield, D-N.C., is the ranking minority subcommittee member.

Google announced last week that it will consolidate dozens of user agreements for its most popular services into one privacy agreement encompassing them all. Starting March 1, the company will have the ability, policywise, to correlate what a user does across most of its online services, whether a user accesses them on PC Web browser or via any Internet-connected mobile device using the Google Android operating system.
