The U.S. official in charge of protecting American elections from hacking says the Russians successfully penetrated the voter registration rolls of several U.S. states prior to the 2016 presidential election.

…In January 2017, just weeks before leaving his post, [Former DHS Secretary Jeh] Johnson declared the nation’s electoral systems part of the nation’s federally protected “critical infrastructure,” a designation that applies to entities like the power grid that could be attacked. It made protecting the electoral systems an official duty of DHS.

But Johnson told NBC News he is now worried that since the 2016 election a lot of states have done little to nothing “to actually harden their cybersecurity.”

…Many of the states complained the federal government did not provide specific threat details, saying that information was classified and state officials did not have proper clearances.

…Other states that NBC contacted said they were still waiting for cybersecurity help from the federal government.

…Some state officials had opposed Johnson’s designation of electoral systems as critical infrastructure, viewing it a federal intrusion.
