I’ve read that it was changed to allow second hand information. Is that incorrect?
The form was clarified to reflect the law, which specifically states that hearsay information is OK.
It doesn't matter, however, because this whistle blower used the old form and claimed to have first hand knowledge of some of the allegations.
Changing the form had nothing to do with this claim.
A change in the law would have to be signed by the president, would it not?
