US revokes Brazilian ambassador's visa amid diplomatic row

In early August 2026, the United States revoked the visa of Brazil's ambassador to Washington, escalating a diplomatic feud between the two countries. The move, carried out by the Trump administration, was seen as a tit-for-tat response in an ongoing spat involving Brazilian President Luiz Inácio Lula da Silva and President Donald Trump.

The visa revocation adds to existing tensions between the US and Brazil, which have been further strained by Trump's looming presence over Brazil's closely fought election. Some commentators have framed the dispute as reflecting Washington's outdated 'backyard' mentality toward Latin America.
