Mitch PerryFILE - In this Sept. 10, 2014 file photo, Sen. Bill Nelson, D-Fla. listens on Capitol Hill in Washington. Democratic senators on Friday called on federal regulators to investigate Verizon Wireless, the countrys biggest mobile provider, for secretly inserting unique tracking codes into the Web traffic of its some 100 million customers. Data privacy experts have accused Verizon of violating consumers privacy by using supercookies, an identifying string of letters and numbers attached to each site visited on a persons mobile device. This whole supercookie business raises the specter of corporations being able to peek into the habits of Americans without their knowledge or consent, said Nelson, the top Democrat on the Senate Commerce Committee, in a statement.
