Two GOP senators — John Thune (R-S.D.) and Jerry Moran (R-Kan.) — have sent a letter to Yahoo CEO Marissa Mayer asking for additional information regarding the company's data breaches, according to The Hill.
Sen. Thune serves as chairman of the Senate Commerce Committee and Sen. Moran is chairman of the panel's consumer protection and data security subcommittee.
In a letter addressed to Ms. Mayer, they wrote, "Despite several inquiries by Committee staff seeking information about the security of Yahoo! user accounts, company officials have thus far been unable to provide answers to many basic questions about the reported breaches. ... Moreover, Yahoo!'s recent, last-minute cancellation of a planned congressional staff briefing originally scheduled for Jan. 31, 2017, has prompted concerns about the company's willingness to deal with Congress with complete candor about these events."
In the letter, Sens. Thune and Moran asked Ms. Mayer to explain what correctional steps Yahoo has taken and which individuals were affected by the breaches.
In September 2016, Yahoo revealed it suffered a data breach in 2014 that affected 500 million users. In December 2016, Yahoo disclosed it was the victim of an August 2013 data breach that affected more than 1 billion users.
