Venezuela's attorney general has announced that National Assembly leader Juan Guaidó, recognized by the U.S. and more than 50 other countries as the country's interim president, is under investigation for an alleged attack on Venezuela's power grid, per AP.

Why it matters: Venezuela has been hit by crippling power outages over the past five days. President Nicolás Maduro tried to blame the U.S. and is now targeting Guaidó, who remains free and whose safety is considered a red line by the Trump administration. Fears of escalation were already growing after Secretary of State Mike Pompeo last night announced an evacuation of the U.S. embassy in Caracas.
