Jeh Johnson, Obama's former Homeland Security secretary, has been asked to testify in front of the House Intelligence Committee regarding their investigation into Russian meddling in the election and potential collusion with Trump's team, per Politico.
The details: Johnson will likely answer questions about any attempts by Russia to hack into U.S. election systems, Politico notes. Earlier this week, Johnson appeared before the Senate Intelligence Committee during a closed testimony. Johnson previously acknowledged that he was aware of some Russian attempts to hack voter registration bases, but he told MSNBC earlier this month that he wasn't certain of any actual changes to vote counts because of Russian interference.
Why it matters: Johnson's testimony could give the House key insights into previous election hacking strategies by Russia, which would better inform their current investigation.
