Exclusive: U.S. and Brazil lawmakers seek to cooperate on investigation of Brasilia riotsWASHINGTON/BRASILIA, Jan 11 (Reuters) - U.S. and Brazilian lawmakers are looking for ways to cooperate on an investigation into violent protests that rampaged through Brasilia this weekend, sharing lessons from inquiries into the attack on the U.S. Capitol, people familiar with the talks said.Supporters of former President Jair Bolsonaro ransacked Brazil's Congress, Supreme Court and presidential palace on Sunday, calling for a military coup to overturn the October election won by President Luiz Inacio Lula da Silva.The source, who is close to Pacheco, said the U.S. embassy's chargé d'affaires, Douglas Koneff, was receptive to the idea of sharing know-how from the investigation of then-President Donald Trump's supporters who attacked the Capitol in a failed attempt to stop Congress from certifying Joe Biden's election win.U.S. Secretary of State Antony Blinken said on Wednesday that Washington had not received any specific requests from Brazil regarding the recent violence in Brasilia, but it would respond "expeditiously" if and when a request arrives.Separately, a group of 74 federal lawmakers in the United States and Brazil released a joint statement on Wednesday condemning the political violence in Brasilia and Washington that came two years and two days apart."
