Markey is one of eight members Thursday that fired off a letter to Google's CEO Larry Page with a long list of questions about what the search giant is doing to protect consumers' privacy rights.
All except one of the eight is a member of the House Energy and Commerce Committee, including ranking member Henry Waxman (D-Calif.), Cliff Stearns (R-Fla.), Joe Barton (R-Texas), Diana DeGette (D-Colo.), Marsha Blackburn (R-Tenn.) and G.K. Butterfield (D-N.C.). Rep. Jackie Speier (D-Calif.) is not a member of the committee, but she represents the district where YouTube is headquartered.
Since Google announced Tuesday it was consolidating its privacy practices into one main policy allowing it to track users across all its products and services, lawmakers and public interest groups raised alarms.
In the letter, lawmakers stressed the importance of Google allowing consumers the ability to opt out of the policy, which goes into effect March 1.
"We believe that consumers should have the ability to opt out of data collection when they are not comfortable with a company's terms of service and that the ability to exercise that choice should be simple and straightforward," wrote the lawmakers.
Google has until Feb. 16 to respond to questions about how it will use the information it collects, who has access to it, whether it will be sold, how long Google will keep the data, whether there are specific provisions to protect children and teens, and how Android users will be affected.
