As evidenced by the summary of the July 25th phone call, it's clear that Trump does believe in the CrowdStrike theory which has been de-bunked all over the internet. In order to believe that theory, you would have to overlook some things which are very easily fact-checked - such as the fact that CrowdStrike is based out of Sunnyvale, California. You would also have to firmly disbelieve the conclusion reached by our intelligence community. Trump really did ask Zelensky to look for the DNC server. It is not the kind of theory that you would expect an intelligent, competent person to believe... much less the President of the United States.
