Article I read said that US Soccer first got the "tip" from the Reynas during the World Cup so before it became public.
EDIT: updated article says US Federation officially got the info from Claudio's wife after it became public but that Claudio supposedly threatened to leak it during the World Cup.
Claudio Reyna also sent multiple messages to USMNT general manager Brian McBride and Stewart during the World Cup, in which he said he shared his frustration about Gio's World Cup experience.
Multiple sources told ESPN he threatened to share allegations about Berhalter's past, but Reyna has denied those allegations.
"While in Qatar, I shared my frustrations about my son's World Cup experience with a number of close friends, Earnie and Brian McBride among them. However, at no time did I ever threaten anyone, nor would I ever do so," he said in Wednesday's statement.
The messages began from Claudio after his son, Gio Reyna, was informed he would have a limited role at the tournament.
