A dossier containing details about timings and locations for the Alaska summit was reportedly found by hotel guests on a printer hours before Donald Trump greeted Vladimir Putin.

The papers, which appeared to have been prepared by US state department staff, included potentially sensitive information about the high-stakes talks.

The eight-page document was found at around 9am on Friday by three guests at Hotel Captain Cook, located around 20 minutes from the Joint Base Elmendorf-Richardson base in Anchorage, according to NPR.
