Biden: US getting closer to identifying document leaker.

US President Joe Biden has said that the investigation into the apparent leak of classified military intelligence documents is "getting close". The documents, which began to appear online in early March, contain information on US assessments of the war in Ukraine and intelligence on close US allies. The man believed to be behind the leaks has been identified as 21-year-old Jack Teixeira, a member of the intelligence wing of the Massachusetts Air National Guard. While unverified, the documents have generated responses from several governments and social media companies have been called on to avoid facilitating the circulation of material detrimental to public safety and national security.
