President Donald Trump’s decision to impose sanctions on Brazil in defense of the country's former president, Jair Bolsonaro, has marked a low point in U.S.

Jair Bolsonaro placed under house arrest by Brazil's Supreme Court after addressing supporters at Rio protest, violating release conditions in election case.

The Brazilian Supreme Court justice’s order could complicate efforts to negotiate over President Trump’s punishing tariffs, set to go into effect this week.
