Brazil named Rio de Janeiro and three other states as host venues for the Copa America on Tuesday in a move that appeared to strengthen the likelihood of the soccer tournament taking place, even as a Supreme Court judge asked President Jair Bolsonaro to explain his surprise decision.

The demand by Justice Ricardo Lewandowski came in response to a suit filed by the opposition Workers' Party, which objected to Brazil hosting the tournament given the current public health situation.

Bolsonaro said earlier on Tuesday his government had agreed Brazil would host the regional tournament from June 13 to July 10, after planned host Argentina pulled out due to a dramatic worsening of the coronavirus pandemic there.
