"I am very deeply troubled by the practices that seem to be spreading voraciously around the country," Blumenthal told Politico. He added that an "employer has a lot of ways to find out information" about potential new employees.
Blumenthal said his bill will have exceptions, including some federal and local law enforcement agencies, as well as national security departments. That being said, he plans to include private companies with government contracts for highly classified work.
Although Facebook didn't explicitly say so, the company is likely supporting Blumenthal. After all, sharing or soliciting a Facebook password is a violation of the social network's Statement of Rights and Responsibilities.
"Facebook takes your privacy seriously," Facebook Chief Privacy Officer for Policy Erin Egan said in a statement. "We'll take action to protect the privacy and security of our users, whether by engaging policymakers or, where appropriate, by initiating legal action, including by shutting down applications that abuse their privileges. While we will continue to do our part, it is important that everyone on Facebook understands they have a right to keep their password to themselves, and we will do our best to protect that right."
I have contacted Facebook about Blumenthal's bill and will update you if I hear back.
Update at 3:25 PM PST: Facebook declined to comment on the bill.
