Upon researching this claim I initially determined that it is essentially factual. Specifically, there was an instance when Donald Trump posted a message on March 26 concerning this claim. Hence, it would seem as though that part of the claim was factually accurate. However, during a follow up evaluation of the claim related to U.S. Intelligence Agencies' interception of communications from Ukraine to support funding of Joe Biden's 2024 presidential election campaign, concerns were raised relative to its credibility.
First, the claim has not been proven through evidence and I could find no evidence verifying the existence of an independent investigation supporting this claim. There is but one unverified article, with no supporting evidence, suggesting intercepted communications exist. Additionally, I have seen no credible reports made by reputable domestic/international news agencies addressing this matter. It seems reasonable to expect if a serious allegation like this existed there would be substantial amounts of consistent reporting from several credible news organizations.
Additionally, allegations of foreign influence in U.S. elections are extremely serious and therefore require substantial, verifiable evidence to lend them credibility. Since I found no such evidence, I am having difficulty accepting this claim without some form of proof. Further still, the method of dissemination through social media and smaller reporting outlets may raise concern and lower the level of believability of this claim.
While Trump posted a message on March 26 referencing this claim, my findings show the original claim is unsubstantiated and likely misleading.
