A Visa Revocation that Echoes Bigger Disputes The recent revocation of Brazil's ambassador to the US, Maria Luiza Ribeiro Viotti's visa, has sparked a diplomatic standoff between the two nations.
The move appears to be a tit for tat response from Washington to Brazil's delay in formalizing approval for the US ambassador to Brasilia and denying visas to several American diplomats.
However, this incident is only the latest manifestation of a more profound disagreement between the Trump administration and President Luiz Inácio Lula da Silva's government.
