Speaker Paul Ryan (R-Wis.) has arranged for top U.S. intelligence officials to brief members of Congress later this week on the Trump administration’s efforts to guard voting systems across the country from hackers. The briefing comes amid increased fears about threats to the 2018 midterm elections following Russian interference in the 2016 presidential race, which U.S. officials have said involved hackers targeting state voting infrastructure. Homeland Security Secretary Kirstjen Nielsen, Director of National Intelligence Daniel Coats and FBI Director Christopher Wray are set to brief lawmakers on Thursday evening, according to an aide to Ryan. The briefing will be unclassified and members-only, meaning it will be closed to the public. The briefing is expected to cover current threats to the U.S. election process and the Department of Homeland Security’s (DHS) ongoing efforts to provide voluntary aid to states to secure their systems. Officials will also discuss what state election officials are doing to secure their respective systems.
