Brazil's Supreme Court was caught off-guard by Justice Alexandre de Moraes' decision late on Monday to place former President Jair Bolsonaro under house arrest, two sources at the court told Reuters on Tuesday.

The trial of the far-right leader is receiving renewed attention after U.S. President Donald Trump directly tied a 50% tariff on imported Brazilian goods to his ally's judicial situation.

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.
