"Rather than rely on Google’s explanations and assurances, our multistate coalition, led by Connecticut, will work to confirm the facts about how this happened and how consumers will be protected going forward," he said.
He said his investigation will continue "until all the facts are verified."
Google last week for the first time confirmed the extent of the privacy breach, stating that it had collected and stored private e-mails and passwords. It says it did so inadvertently due to problematic software.
The admission, Blumenthal said, "only heightened our concerns about how and why this data was collected."
“Google’s story has changed during the course of our multistate investigation — demonstrating the need for sustained scrutiny.”
