Votes in several states on Tuesday could offer a glimmer of hope to Democrats

Film director Oliver Stone will testify at a US House of Representatives hearing on Tuesday that is considering thousands of pages of documents related to the 1963 assassination of John F Kennedy released this month at the direction of President Donald Trump.

Representative Anna Paulina Luna, chair of the Task Force on the Declassification of Federal Secrets, said that lawmakers will hear from witnesses about the value of the documents.
