The United States has revoked the visa of Brazil’s ambassador to Washington D.C. This action is a direct response to Brazil's decision not to formally recognize the appointment of the new U.S. ambassador. Furthermore, Brazil has declined to issue visas to two other American officials. According to an unnamed U.S. official, the revocation is a retaliatory measure. The move escalates a growing diplomatic dispute between the two countries. Both the Associated Press and Reuters reported on the situation, citing the anonymous source. This reciprocal action signals a deepening strain in US-Brazil relations.
