In his resignation letter Monday, Deputy Attorney General Rod Rosenstein claimed “our elections are more secure,” just days after FBI Director Christopher Wray said Russia’s efforts to influence the U.S. electorate “has absolutely continued” since 2016.

“It’s pretty much a 365-days-a-year threat,” Wray said at a Council on Foreign Relations event last week.

“We recognize our adversaries will keep upping their game,” said Wray. “2018 was just a dress rehearsal for 2020.”

Last week Sen. Marco Rubio, R-Fla., confirmed that Russian hackers had accessed a Florida county’s voter registration system but that the authorities chose to keep the breach hidden from Florida officials to protect intelligence methods, a tactic the senator seemed to defend.

“Everybody has been told what it is they need to do to protect themselves from the intrusion,” Rubio told the New York Times. “I don’t believe the specific victims of the intrusion have been notified.”

Rosenstein said in his letter posted by NPR that U.S. citizens are better informed and more aware of “covert efforts and schemes to commit fraud, steal intellectual property, and launch cyberattacks.”
