January 8: A new date of infamy. Supporters of right-wing former President Jair Bolsonaro who falsely allege last year’s election was stolen stormed Brazil’s Congress, Supreme Court, and Presidential Palace in Brasília on Sunday.

Police cleared the buildings and made hundreds of arrests. But as the tear gas clears, substantial questions remain about the state of Brazil’s democracy and institutions—and what the United States can do in response to the riot. Our experts are on the case.
