The US authorities are investigating the leak of hundreds of secret US defence documents, some of which related to the war in Ukraine.
The Guardian’s investigations correspondent, Manisha Ganguly, tells Hannah Moore how these documents migrated between different websites before being picked up by the press. Julian Borger, the Guardian’s world affairs editor, explains what we learned from the leak and how the US authorities have responded.
On Friday, Jack Teixeira of the air national guard was charged on two counts under the Espionage Act.
