By Noreen Jazul  Justice Secretary Menardo Guevarra said the United States (US) State Department must be "convinced" first that Senator Leila de Lima was wrongfully imprisoned before the travel ban on persons allegedly involved in her detention is implemented. Justice Secretary Menardo Guevarra (TOTO LOZANO / PRESIDENTIAL PHOTO / FILE PHOTO / MANILA BULLETIN) "If they believe that in fact, Sen. de Lima was not given due process and that she was wrongfully imprisoned, then the State Department can start identifying and evaluating these people who might have...had involvement in this alleged wrongful detention," Guevarra told CNN Philippines Wednesday. Guevarra said it was clear that US senators Edward Markey , Dick Durbin and Patrick Leahy believe that de Lima was wrongefully detained so he invited their staff, through a public statement, to come to the Philippines and examine the records of the lady senator's case. "I invited their staff, 'why don't you come over?' examine the records, read the transcript, observe the proceedings, and tell us whether she's wrongfully detained... no reaction," Guevarra said. When asked what he would feel if he was included in de Lima's list of officials responsible for her detention, the Justice Secretary said: "I don't really mind." "It's the prerogative on the part of the US government whom to bar or who to allow entry. They don’t even have to refer to all of these senate resolutions because that's their prerogative, they don’t even have to have a standard by which to measure kung papasukin or not this particular person," he added. Guevarra, meanwhile, said there was "nothing wrong" with President Duterte's proposal to require Americans to obtain a visa before entering the Philippines on the "basis on the reciprocity." "US has always demanded that Filipinos who want to go to the US must obtain a US visa, what's wrong with demanding the same from them?" he said.
