President Joe Biden welcomed Brazilian President Luiz Inácio Lula da Silva to Washington on Friday for wide-ranging talks on climate and strengthening democracies, an issue of shared importance after both leaders faced far-right mobs storming their governments' halls of power to try to overturn their election victories. Biden defeated incumbent Donald Trump in a fraught 2020 race, securing victory with thin margins in several battleground states. In Brazil's recent election, its tightest since its return to democracy over three decades ago, Lula, the leftist leader of the Workers' Party, squeaked out a win against right-wing incumbent Jair Bolsonaro, who earned the nickname "Trump of the Tropics" and was an outspoken admirer of the former U.S. president.
