At an Oct. 10 Senate Commerce hearing on consumer data privacy, Sen. Richard Blumenthal, said that he intends to send a letter later in the day to the Federal Trade Commission calling on them to investigate Alphabet Inc.'s Google LLC over a data breach that was confirmed by the company on Oct. 8.

In a blog post regarding the breach, the company said it discovered in March a bug that shared some users' profile data from the seldom-used Google+ social network, which it is subsequently shuttering.

"Until there is an effective enforcer at the federal or state level, with federal standards backed by strong resources and authority, consumers will continue to be at risk,” said Blumenthal, a Democrat from Connecticut who serves as ranking member on the Subcommittee on Consumer Protection, Product Safety, Insurance and Data Security. "I will be calling later today in a letter to the FTC for an investigation of Google in connection with this incident. I hope to be joined by a number of my colleagues," he said.

Blumenthal also called the company’s failure to disclose the breach for several months a "violation of basic norms," and said he hopes that European authorities will also investigate the breach.
