All eyes will be on the Obama administration as the public presses for answers about the ever-widening scope of the data breach at the Office of Personnel Management.
It was revealed Thursday that up to 14 million people potentially including every current and former member of the federal government, government contractors and people named in background checks may have had their personal information exposed by the hack.
When the hack was first announced in early June, the OPM said it believed hackers had gotten the records of 4 million current and former executive branch workers. But rumblings grew throughout this past week that more records were involved, with estimates ranging from 9 million to 14 million.
Those worries were compounded late Friday by reports of a second separate breach that may have given Chinese-backed hackers access to security clearance information for millions of intelligence and military personnel.
The House Oversight and Government Reform Committee will try to get some specifics from the administration during a Tuesday hearing.
A slate of top administration officials are expected to testify, including Homeland Security Secretary Jeh Johnson and the chief information officers for the OPM, Office of Management and Budget and the Interior Department, which housed the data center that was compromised.
Over in the Senate, Republican leaders will look to reassess and figure out how to move forward with a cybersecurity measure after failing to attach it to the annual defense authorization bill.
Senate Majority Leader Mitch McConnell (R-Ky.) had wanted to link a cyber bill intended to facilitate the public-private exchange of information on hackers to the National Defense Authorization Act (NDAA).
The move was an attempt to rush the measure, known as the Cybersecurity Information Sharing Act (CISA), through Congress in the wake of the OPM breach.
But Democrats balked at the maneuver, arguing they should have the chance to offer privacy-enhancing amendments.
Several surveillance critics, including Sens. Patrick Leahy (D-Vt.) and Ron Wyden (D-Ore.), had pledged to alter the bill on the floor to quell fears that it would simply shuttle more sensitive data to the National Security Agency.
Democrats mustered just enough votes to block the move to attach the bills language to the NDAA, causing Senate Armed Services Committee Chairman John McCain (R-Ariz.) to withdraw the amendment.
Senate Minority Leader Harry Reid (D-Nev.) has called for the Senate to take up CISA immediately following the conclusion of the NDAA debate. But McConnell rejected that plan on the Senate floor, leaving it unclear what Republicans next move is for the cyber bill.
We have a plan A and a plan B, Senate Majority Whip John Cornyn (R-Texas) told reporters shortly before Democrats stymied plan A. Our plan B is plan A.
