The House is taking a weeklong break, but the Senate will be in high gear tackling a number of issues related to cybersecurity.

All eyes will fall on a Senate Judiciary subcommittee headed by Sen. Lindsey Graham Lindsey Olin GrahamSenate Republicans signal openness to working with Biden Loeffler calls for hearing in wake of Netflix's 'Cuties' Quinnipiac poll shows Graham, Harrison tied in South Carolina Senate race MORE (R-S.C.) that will hear testimony Monday afternoon from former Obama administration officials on Russia's interference in the 2016 presidential election.

Sally Yates, the former acting attorney general who was fired by President Trump over her refusal to back his controversial immigration executive order, is expected to give her account of the warning she gave to the White House over former national security adviser Michael Flynn's contacts with the Russian ambassador to the U.S. Sergey Kislyak.

It has been reported that Yates informed the White House that Flynn may have misled the administration about the content of his communications with Kislyak weeks before he was forced to resign over the issue. The Washington Post reported in February that Flynn discussed sanctions in phone calls with Kislyak, despite Vice President Mike Pence Michael (Mike) Richard PenceGOP short of votes on Trump's controversial Fed pick Pence seeks to boost Daines in critical Montana Senate race The Hill's Campaign Report: Trump's rally risk | Biden ramps up legal team | Biden hits Trump over climate policy MORE denying it publicly.

Anticipation for Yates' testimony has been high, ever since House Intelligence Committee Chair Devin Nunes (R-Calif.) cancelled a scheduled public hearing with Yates and others in March allegedly to make room for a closed hearing that never happened --until Wednesday.

The Senate subcommittee hearing will also feature former director of national intelligence James Clapper.

The subcommittee is one of multiple panels in both chambers of Congress investigating Russia's interference campaign aimed at the election. The House Intelligence Committee has apparently gotten its investigation back on track after Nunes' recusal following his controversial claims about incidental surveillance collection on associates of Trump.

The new leader of the House investigation--Rep. Mike Conaway (R-Texas)--has also summoned Yates to testify, likely satisfying his Democratic colleagues. The panel heard from FBI Director James Comey and NSA Director Adm. Mike Rogers behind closed doors on Wednesday.

Rogers heads back to the Hill on Tuesday, to offer his input to members of the Senate Armed Services Committee on the U.S. Cyber Command.

Rogers serves the dual-hat leadership role of NSA director and commander of Cyber Command. The two organizations have been joined ever since Cyber Command grew out of NSA headquarters in 2009.

The two organizations eventually expect to be separated, in the wake of Cyber Command being spun out as its own warfighting unit. Congress has directed the Pentagon to assess the possibility of the split.

The Senate Committee on Homeland Security and Governmental Affairs will explore cyber threats facing the nation on Wednesday, fielding expert testimony from four different authorities on cybersecurity.
