text: Information can be evidence when gathered by intelligence agencies or the FBI. Intelligence agencies use a broader definition of evidence out of necessity because that is the nature of what they do-- relying on sources they may not know well and documents they may not be able to verify-- this broader evidence is what we want to identity things like terrorist threats or actions by the Russians to interfere in our elections. The FBI which prosecutes people in criminal courts needs evidence which proves beyond a reasonable doubt-- this is what is needed to prosecute Trump campaign persons suspected of collusion.
