US Pulls Brazilian Ambassador's Visa Over Blocked Nominee

On August 4, 2026, the Trump administration revoked Brazilian Ambassador Maria Luiza Ribeiro Viotti's visa. The State Department linked the move to Brazil's refusal to approve Daniel Perez, Trump's pick for US ambassador to Brazil, and Brazil's July denial of visas for two US diplomats. The visa could be restored if Brazil accepts Perez. Brazil called the action "ideologically motivated" and won't decide on Perez before its October 4 election.
