Venezuelan opposition leader Juan Guaidó posted a video to Twitter on Tuesday calling for a military uprising while surrounded by soldiers and a detained activist, per the AP.

Why it matters: Guaidó's stance against Venezuelan President Nicolás Maduro has so far been relatively peaceful, but Tuesday's video marks a significant escalation in his strategy — which the Trump administration "fully supports," according to Secretary of State Mike Pompeo. While the scope of Guaidó's support among the Venezuelan military is not yet known, the AP reported that Maduro's government said it was putting down a coup instigated by "traitors" linked to Guaidó.

The big picture: Perhaps 80 million Americans will vote early, by mail or in person, Tom Bonier, CEO of TargetSmart, a Democratic political data firm, tells Axios. That's going to set up more of an Election Season than an Election Day — and increase the odds of national turmoil over the vote count.
