President Obama's homeland security chief is telling Congress what he knew about Russian meddling in last November's election.
FOX's Jared Halpern has more from Capitol Hill:
Former Homeland Security Secretary Jeh Johnson has been pressed, particularly by House Intelligence Committee Democrats, on why intelligence officials waited until October to publicly acknowledge Russia's role in election-related cyber-attacks:
(Johnson) "We have to carefully consider whether declassifying intelligence compromises sources and methods. second, there was an ongoing election and many would criticize us for perhaps taking sides."
Johnson says there's no evidence votes were altered by cyber-attacks...but is warning about potential vulnerabilities in election infrastructure.
