This second individual has reportedly confirmed what the first whistleblower claimed with the added advantage that he/she directly witnessed some of the events in question.
With the first whistleblower set to testify soon in a closed session before the House Intelligence Committee, hopefully soon the second one will do the same.
Yesterday, one of the attorneys representing both whistleblowers hinted during a media interview that there's at least a third and possibly more whistleblowers waiting in the wings.
Hopefully we'll see more reporting soon on these fascinating developments. Stay tuned.
