Seems a LOT of folks (even here) are missing the alleged “fact” there was no direct knowledge by the so called whistleblower. Guess having a strong dislike for PDJT is enough though these days.
Apparently it is for the Intelligence Community IG who found the complaint to be credible. That's the person who's the real problem in all of this. His name is Michael K. Atkinson and his official bio shows he's a Deep Stater:
Michael K. Atkinson was sworn in as the Inspector General of the Intelligence Community on May 17, 2018, following his confirmation by the U.S. Senate. As Inspector General, Mr. Atkinson oversees a workforce of special agents, auditors, inspectors, attorneys, and support staff whose mission is to promote economy, efficiency, and effectiveness in the administration and implementation of programs and activities within the responsibility and authority of the Director of National Intelligence and to prevent and detect fraud and abuse in such programs and activities. He also serves as the Chair of the Intelligence Community Inspectors General Forum, which consists of the twelve inspectors general with oversight responsibility for elements of the intelligence community. The Forum serves as a mechanism for informing its members of the work of individual members of the Forum that may be of common interest and discussing questions that may involve or be of assistance to more than one of its members.Another self-inflicted appointment of a Deep Stater wound by the Trump administration.Prior to his Senate confirmation, Mr. Atkinson worked for the U.S. Department of Justice for over fifteen years. He worked as a Trial Attorney in DOJ’s Criminal Division, Fraud Section, from 2002 through 2006. He then served as an Assistant United States Attorney for the District of Columbia from 2006 through 2016, where he was the Acting Chief and Deputy Chief of the Fraud and Public Corruption Section. In 2012, he was awarded the Attorney General’s Award for Distinguished Service for his work on a significant public corruption case. Thereafter, he served in DOJ’s National Security Division as the Acting Deputy Assistant Attorney General for National Asset Protection and as Senior Counsel to the Assistant Attorney General.
