New York, Oct 27 WikiLeaks has offered $100,000 reward to anyone who can provide them with the redacted parts of the files relating to the assassination of US President John F Kennedy. The whistleblower organisation announced this in a tweet: "WikiLeaks issues a $100,000 reward for the withheld JFK documents should they show violations of law, inefficiency, or administrative error." The offer was made on Friday after nearly 2,900 of the JFK assassination files were released on Thursday night. Around 200 documents have been held back by federal agencies as they say they pose a risk to national security, a fact which is said to have displeased President Donald Trump. WikiLeaks founder Julian Assange tweeted: "The agencies have had literally 25 years to prepare for the scheduled release today. The delay is inexcusable. @realDonaldTrump." President Trump in a tweet said: "JFK Files are being carefully released. In the end there will be great transparency. It is my hope to get just about everything to public!"
