By Jennifer Hansler, CNN(CNN) — The Trump administration has revoked the visa of Brazil’s ambassador to the US, escalating a rift between Washington and Brasilia. The State Department did not declare Amb. Another senior State Department official said that if Viotti leaves the US, she would need to reapply for a visa. Lula said last month the Brazilian government refused to grant visas to two State Department officials because of concerns about election meddling. The first senior State Department official said Tuesday that the officials were planning a “routine trip.”
