In his ongoing attempt to smear the whistle-blower, Donald Trump has insisted that the individual from the intelligence community who filed a complaint against him can’t be trusted because the person had only secondhand knowledge of his call with the president of Ukraine. You know, the one in which he pressured Volodymyr Zelensky to investigate his political rival in exchange for nearly $400 million in military aid, at a time when the Eastern European country really, really needed the money. That the whistle-blower’s complaint is yet to be disproved, and closely matches the readout released by the White House, is apparently of little interest to the president, who insists the person knows nothing because they weren’t on the call. One person—of many—who was? The whistle-blower’s source, who was apparently completely freaked out about what he’d heard from the president of the United States, according to the memo written by the whistle-blower one day after the July 25 call.

The New York Times reports that the White House official who confided in the CIA officer described Trump’s conversation with Zelensky as “crazy,” “frightening,” and “completely lacking in substance related to national security.” The official was apparently “visibly shaken by what had transpired” and “seemed keen to inform a trusted colleague within the national security apparatus about the call.” In the two-page memo, handed over to Congress last week by Inspector General Michael Atkinson, along with other documents, the officer writes that he spoke with the White House official for only a few minutes, “and as a result, I only received highlights.” The whistle-blower went on to speak to “multiple U.S. government officials” before filing his complaint that charged that Trump was “using the power of his office to solicit interference from a foreign country in the 2020 U.S. election.” Atkinson reportedly interviewed numerous people who deemed the complaint credible.

While the details of the complaint have been largely corroborated by the rough transcript released by the White House, some are left wondering what Team Trump chose not to include. Earlier this month, the Washington Post wrote that current and former U.S. officials who studied the readout “pointed to several elements that, they say, indicate that the document may have been handled in an unusual way,” including the use of ellipses, during key sections of the call, “that traditionally have not appeared in summaries of presidential calls with foreign leaders,” as well as the fact that the document appears to be that of a roughly 10-minute call, rather than the 30 minutes for which the two men spoke.

Of course, that a person literally listening in on the conversation was apparently deeply shaken by it will be of little import to Trump, who is attempting to smear the whistle-blower on multiple fronts, including the individual’s alleged political affiliation. Per the Times:
