An opposition congresswoman close to the prosecutor whose mysterious death has rocked Argentina says he told her the government was going to remove him from his post because of a case he was building against President Cristina Fernandez.

Laura Alonso made the comments Friday after meeting with investigators.

Prosecutor Alberto Nisman was found shot dead in his bathroom on Jan. 18. The discovery came shortly before he was to appear in Congress to detail his allegations that Fernandez helped Iran cover up the 1994 bombing of a Jewish community center, which killed 85. Fernandez and Iran deny the accusations.

Alonso said Nisman spoke to her privately on Jan. 14. She said he feared for his safety and for his daughters, confirming what several other Nisman friends and colleagues have said.
