The claim that Donald Trump said he used presidential power to have James Comey arrested and warned critics and iran is not supported by any credible evidence. After looking at primary sources including Trumps public speeches, interviews, social media posts, and official statements there is no record of Trump stating this. James Comey has not been arrested and no major credible news organization has reported on this. The claim is misleading.
My primary source that I used to research this claim is Trumps truth social and public statements:
https://truthsocial.com/. I looked at this and could not find any verified statements that claimes to have ordered James Comey to be arrested. Trump has publicly criticized Comey multiple times, but critisism is much different than claiming to arrest someone through presidential power. A second primary source that I used is the FBI/DOJ information records:
https://www.fbi.gov/. There are no official DOJ or FBI records that show James Comey was arrested. If this was true, there would be record of that on this website and these are credible government sources that can be trusted to have this information if true.
In conclusion, there is no plausable evidence that can confrim this statement, and this original claim was through social media which can spread edited or misleading information quickly.
