The son of Brazil's former President Jair Bolsonaro has praised US President Donald Trump for imposing huge tariffs on his home country - and warned more measures could be on the way.

Eduardo Bolsonaro - who is an elected Congressman in Brazil - spoke to the BBC in Washington, where he has been on a months-long lobbying campaign to convince the Trump administration to punish the Brazilian authorities for putting his father on trial on coup charges.

The congressman said there could be more sanctions on individuals.

"There's a very significant possibility regarding the application of sanctions and the extension of Magnitsky sanctions to other people. You have on Secretary Marco Rubio's desk, for example, the possibility of withdrawing visas, among other pressure mechanisms, to try to get Brazil out of this institutional crisis we're experiencing."

At the White House Thursday, President Trump doubled down accusing Brazil of being a bad trade partner. He wrongly claimed the US runs a trade deficit with Brazil. Last year, it ran a $7.4 billion trade surplus with Brazil
