(CNN) Secrecy has always been Donald Trump's thing. His net worth? It's hidden in private companies that produce no reliable public reports. His charitable giving? Listed on tax forms that were also kept secret. Profits on investments? Indebtedness? Business traffic at his properties? Secret. Secret. Secret. How ironic, then, that he's now on the path to possible impeachment thanks to what looks like a scheme he couldn't hide.

Trump's presidency is threatened by the secrets revealed by a whistleblower inside the national security community who reported that the President was seeking foreign help to get dirt on his Democratic rival, former Vice President Joe Biden. The whistleblower's complaint drew attention to the now-infamous call Trump had with Ukrainian President Volodymyr Zelensky on July 25.

As a record released by the White House shows, Trump used the call to ask the Ukrainian government to investigate two conspiracy theories for which there is no evidence. The first holds that Ukraine and not Russia waged an information war on America's 2016 election. The second suggests that Joe Biden and his son Hunter Biden were involved in some sort of wrongdoing related to Ukraine's energy industry.

Couched in the words "do us a favor," Trump's requests followed the administration's halt of the transfer of about $400 million in aid scheduled to help Ukraine defend against a Russian-backed armed rebellion in its east. In a classic display of Trumpspeak, the President told Zelensky, "there's a lot of talk" about Biden and he hoped Ukraine would help Attorney General William Barr's probe into it.
