Brazil’s President Dilma Rousseff has canceled her trip to the U.S. over spying by the National Security Agency.

The news was first reported by O Globo on Tuesday and later confirmed in an official statement by the Brazilian government.

Signs had emerged earlier this month that Rousseff would cancel the state visit scheduled for October 23,  including a statement from one unnamed Brazilian official who said of the spying scandal,  “This is a major, major crisis …. There needs to be an apology. It needs to be public. Without that, it’s basically impossible for her to go to Washington in October.”

Rousseff had a 20-minute phone conversation with President Obama on Monday to discuss the revelations that the NSA had spied on Latin American citizens including the presidents of Brazil and Mexico, but Rousseff was unsatisfied with Obama’s explanations for the surveillance, the Brazilian newspaper reported.
