Former Argentine President Cristina Fernandez is going before a federal judge to answer questions in a state fraud probe.

Thousands of supporters gathered outside the courthouse Wednesday and cheered as Fernandez was ushered inside for closed-door questioning. Supporters are holding signs that say "Don't touch Cristina!"

Judge Claudio Bonadio called Fernandez to testify about her alleged role in the central bank's decision to sell dollars on the futures market at an artificially low price in the months before leaving office in December. At the time, there was a large gap between the official rate of the peso against the dollar and the rate on the booming black market.

Bonadio says selling dollars below market rate cost the state about $5.2 billion. Fernandez has denied any wrongdoing.
