Suspended Brazilian President Dilma Rousseff has denied allegations of manipulating government accounts, during testimony at her impeachment trial.
"I did not commit the crimes that I am unjustly accused of," the 68-year-old leftist leader said in an address Monday to the Senate, repeating her claim that the impeachment drive was a "coup."
"I can't help but taste the bitterness of injustice," she said.
Rousseff is accused of taking illegal state loans to cover deficits in the budget.

Former Finance Minister Nelson Henrique Barbosa and Rio de Janeiro State University law professor Ricardo Lodi were brought in to testify and said Rousseff did not break the law.

Following days of deliberations, senators will vote on whether to permanently remove Rousseff. Of the 81 senators, 54 must vote against her in order for the impeachment to become permanent.
