MEMPHIS, Tenn. (AP) — Lawyers for a journalist who was arrested in Tennessee and then placed in an immigration detention facility said Monday that the government was trying to suppress his reporting and violated his rights of freedom of speech and the press. Attorneys with the Southern Poverty Law Center have asked a federal court to release Manuel Duran Ortega, a reporter who was arrested earlier this month in Memphis during a demonstration that coincided with days of remembrance of the 50th anniversary of the assassination of Dr. Martin Luther King in that city. Duran, 42, was working for Spanish-language media outlet Memphis Noticias and has written stories raising questions about local police and their cooperation with federal immigration officials, one of his attorneys at the SPLC said.
