WASHINGTON, United States (AFP) — US security officials warned Tuesday that foreign adversaries would attempt to interfere in the 2020 elections, reprising those of three years ago when Moscow is accused of helping President Donald Trump’s campaign.

In a joint statement the heads of seven top security-related agencies, including the Defense Department, Directorate of National Intelligence and the Federal Bureau of Investigation, said there was no evidence yet of compromise or disruption of the national and state-level election infrastructure that would affect vote counts.

Nevertheless, they said, “Our adversaries want to undermine our democratic institutions, influence public sentiment and affect government policies.”

“Russia, China, Iran and other foreign malicious actors all will seek to interfere in the voting process or influence voter perceptions.”

The statement, which came on the day of a number of off-year elections around the country, served as a reminder of the impact of Russia’s efforts in 2016, which continue to reverberate through the US political scene.
