Colombian Senator Piedad Córdoba Monday told French TV station LCI she has "restrictions regarding their role" of conveying the proof of life of French-Colombian citizen Ingrid Betancourt, a hostage held the rebel Colombian Revolutionary Armed Forces (FARC), and she would rather let "President Hugo Chávez inform about this issue."

Córdoba's statements came during a phone interview with the TV station shortly after her arrival in Paris, AFP reported.

Córdoba, together with the Venezuelan ruler, are mediating for the Colombian government and the FARC to reach an agreement to swap hostages for FARC rebels who are in jail.

Córdoba was commissioned by Chávez to deliver to Caracas a proof of life of Betancourt.

Chávez is engaged in an international tour and had to leave Caracas before the evidence came. Therefore, Córdoba had to travel to Caracas and then to Paris, where she is meeting with Chávez and French President Nicolas Sarkozy.
