Peruvian journalist Walter Chávez, widely named in the press as a key campaign advisor to Bolivian president Evo Morales, was arrested in Argentina March 16, and may face extradition to Peru, where he faces charges of having served as an operative of the Tupac Amaru Revolutionary Movement (MRTA), a now-defunct guerilla group. Chávez was granted political asylum in Bolivia in 1992, and worked on Morales' campaigns between his election in 2005 and his most recent re-election in 2014. Bolivia refused a Peruvian extradition request in 2007. Chávez was arrested in Argentina's northern city of Salta, apparently having crossed the border some three weeks earlier. (Peru.com, March 17; InfoBae, Argentina, Eju!, Bolivia, March 16) In response to the controversy, Bolivia's cabinet chief Carlos Romero denied that Walter Chávez had ever been an official advisor, saying he did not work out of the presidential palace but "particiapted voluntarily" in Morales' campaigns.
