Brazil’s President Jair Bolsonaro got a rousing reception from tens of thousands of people gathered in the capital Tuesday in an Independence Day show of support for the right-wing leader embroiled in a feud with the country’s Supreme Court.

Bolsonaro, in an address inaudible to many in the crowd far from the loudspeakers, lashed out at the high court and said the nation can no longer accept what he characterized as political imprisonments — a reference to arrests ordered by Justice Alexandre de Moraes. He warned that the court could “suffer what we don’t want.”

The crowd began chanting, “Alexandre out!”

His speech followed a helicopter flyover, with those on the ground seized with euphoria at the sight. They applauded and shouted, “Legend!” and “I authorize!” — a slogan widely understood as blanket approval of his methods.

Bolsonaro has called on the Senate to impeach de Moraes, who has jailed several of the president’s supporters for allegedly financing, organizing or inciting violence or disseminating false information.

Massive participation in rallies scheduled across the country would reinforce Bolsonaro’s push to prove he retains strength — despite slumping poll ratings — and recover momentum after a string of setbacks.
