A pair of House lawmakers from Florida have introduced new legislation that would require the Department of Homeland Security (DHS) to notify voters and other parties of potential breaches to election systems.

Reps. Stephanie Murphy (D) and Mike Waltz (R) introduced their measure following revelations earlier this year that Russia infiltrated computer networks in two counties in the Sunshine State ahead of the 2016 presidential election.

Members of the Florida congressional delegation blasted federal agencies in May for their lack of transparency about the cyberattacks, saying they only received an FBI briefing on the matter when former special counsel Robert Mueller revealed in his report that the bureau was investigating a Moscow-led hack into “at least one” Florida county.

The FBI, which informed the Florida delegation that Russia had infiltrated a second county, has not permitted the members of Congress to reveal the names of which counties were targeted.

Murphy and Waltz have called that decision counterproductive, arguing that failing to provide notification about the attack on Florida’s election systems has begun to erode public confidence in the state’s elections
