Go read the DNI's letter. It's very clear, unlike how you're trying to portray it.

"The Complainant on the form he or she submitted on August 12, 2019 in fact checked two relevant boxes: The first box stated that, “I have personal and/or direct knowledge of events or records involved”; and the second box stated that, “Other employees have told me about events or records involved.”
As part of his determination that the urgent concern appeared credible, the Inspector General of the Intelligence Community determined that the Complainant had official and authorized access to the information and sources referenced in the Complainant’s Letter and Classified Appendix, including direct knowledge of certain alleged conduct, and that the Complainant has subject matter expertise related to much of the material information provided in the Complainant’s Letter and Classified Appendix. In short, the ICIG did not find that the Complainant could “provide nothing more than second-hand or unsubstantiated assertions,” which would have made it much harder, and significantly less likely, for the Inspector General to determine in a 14-calendar day review period that the complaint “appeared credible,” as required by statute. Therefore, although the Complainant’s Letter acknowledged that the Complainant was not a direct witness to the President’s July 25, 2019, telephone call with the Ukrainian President, the Inspector General of the Intelligence Community determined that other information obtained during the ICIG’s preliminary review supported the Complainant’s allegations."
