Concern After Argentina's President Long Silence Print article Send a Tip from AP 16 Jan 2014 post a comment (AP) Concern after Argentina's president long silence BUENOS AIRES, Argentina A puzzling silence has descended around Argentine President Cristina Fernandez. It's been 37 days since she last spoke in public. And she hasn't posted any message to Twitter since Dec. 13, when she fired off a typical volley of 20 tweets. That's feeding speculation in Argentina about her health and questions about who's running the country. Members of Fernandez's administration dismiss the questions. They say she's continued to meet with officials. Defense Minister Agustin Rossi said Thursday that "the president is totally in command." Fernandez was long known for nearly daily speeches and constant tweets. But she was silenced for six weeks late last year when she underwent surgery to remove a blood clot. She returned to work in mid-November.
