After Mueller, questions loom about 2020 election security

ATLANTA (AP) — With the end of the special counsel’s investigation of Russian interference in the 2016 race for the White House, election security experts are wondering whether the U.S. is doing enough to fend off an attack in 2020.

The special counsel’s probe ended last week with the conclusion there was no coordination with the Trump campaign.

But the 22-month-long investigation underscored how vulnerable the U.S. was to a foreign adversary seeking to sow discord, spread misinformation and exploit security gaps in state election systems.

What happened in 2016 has trigged a wide range of actions by social media companies and federal, state and local officials.

But security experts and elected officials wonder whether the federal government and the states have done what they need to do to thwart another attack by Russia or other hostile foreign actors.
