Apple and Google will return to the Hill this week to talk about mobile privacy, and this time they’ll be joined by a representative from Facebook.

The Senate commerce committee, chaired by Sen. Jay Rockefeller (D-W.Va.), announced Monday that its consumer protection subcommittee will hold a hearing on mobile privacy on Thursday. The hearing will examine industry practices relating to online mobile data collection and consumer privacy rights and expectations.

The lineup of speakers is similar to that at last week’s Senate Judiciary subcommittee hearing on mobile privacy, with representatives from Apple; Google; the Association for Competitive Technology, a lobbying group for app developers; and the Federal Trade Commission’s Consumer Protection Bureau.

Apple and Google faced close scrutiny from lawmakers at the Judiciary hearing over how much control consumers have over their own data and how much of the data can be traced back to specific customers. Both companies said that they clearly inform users about their privacy options and that the data collected is anonymous.

Google’s Alan Davidson, who spoke at the last hearing, will return to the Hill this week. Apple will be represented by Catherine Novelli, the company’s vice president of worldwide government affairs. Facebook’s chief technology officer, Bret Taylor, and Common Sense Media’s Amy Guggenheim Shenkan will also speak at the hearing.
