WASHINGTON - US President Donald Trump said the United States holds Venezuelan President Nicolas Maduro 'personally responsible' for the health and safety of two leading opponents of his government jailed on Tuesday. In a statement issued by the White House late on Tuesday, Trump said Leopoldo Lopez and Antonio Ledezma were political prisoners held illegally by the Venezuelan government. 'The United States holds Maduro –- who publicly announced just hours earlier that he would move against his political opposition –- personally responsible for the health and safety of Mr. Lopez, Mr. Ledezma, and any others seized,' Trump said.
