That ABC article’s a little light on details. Reuters just published an update:
“Brazil’s Bolsonaro avoids concession to Lula, but transition to begin
BRASILIA/SAO PAULO, Nov 1 (Reuters) - Brazil’s far-right President Jair Bolsonaro on Tuesday avoided conceding defeat in his first public remarks since losing Sunday’s election, saying protests since then were the fruit of “indignation and a sense of injustice” over the vote.
His chief of staff, Ciro Nogueira, speaking after Bolsonaro’s brief public address, said Bolsonaro had authorized him to begin the transition process with representatives of leftist Luiz Inacio Lula da Silva.”
