US Senate Confirms Daniel Perez as Brazil Ambassador

What Did the US Senate Decide About the Brazil Ambassadorship?

The US Senate confirmed Daniel Perez as the next US Ambassador to Brazil on Friday, August 7, by a narrow vote of 51 in favour and 47 against. The vote clears the final domestic hurdle in the United States, but Perez still cannot take up his post without Brazil's formal approval.

What Is the Agrément and Why Does It Matter?

Under international diplomatic convention, a host country must grant an agrément — a formal authorisation — before a foreign ambassador can assume duties. Brazil's foreign ministry, the Itamaraty, has not yet issued that clearance for Perez, meaning the appointment remains on hold despite Senate confirmation.

How Did the Diplomatic Row Start?

President Donald Trump nominated Perez, the son of Cuban immigrants, in June 2025 to fill a vacancy that had existed since Trump returned to the White House in January 2025. Tensions flared when the White House publicly announced Perez's name before completing the customary private diplomatic consultations with Brazil — a step Itamaraty considered a breach of protocol.

How Did the Situation Escalate?

Washington grew impatient over Brazil's delay in granting the agrément and began pressing Brasília for a response. Brazil maintained the request was being processed through normal diplomatic channels. The standoff worsened on August 4, when the US State Department revoked the visa of Brazil's Ambassador to Washington, Maria Luiza Ribeiro Viotti, framing it as a direct response to the delay. The US also signalled the decision could be reversed if Brazil granted the agrément. The visa revocation came ten days after Itamaraty denied visas to two US State Department diplomats who, according to The Washington Post, were part of a strategy to question Brazil's electoral system — an allegation Washington denied. Brazil's government described the escalating measures as a series of hostile actions and rejected the use of the Perez nomination as a pressure tool.

What Happens Next?

With Senate confirmation secured, all remaining steps now rest with Brazil. The Itamaraty can grant or refuse the agrément. Until that decision is made, the US Embassy in Brasília will continue to operate without a confirmed ambassador.
