Emails, text messages, and photographs published by DailyMail.com are among a wealth of evidence that prosecutors could use at trial if Hunter Biden is charged with tax crimes and lying on gun purchase documents.

The FBI believes it has enough evidence to charge Hunter Biden with failure to declare income from his foreign business deals and a failure to declare he was a drug addict on a gun application, sources told The Washington Post Thursday. 

Agents told the Post they assembled enough evidence for a criminal case against the First Son 'months ago' – and the decision to charge now lies with federal prosecutors.
