Investigations are not the same as denying a loss. The investigations were brought on by twump and his crime family himself. The "Russia Hoax" as you call it. There were literally hundreds of contacts between the 2016 twump campaign and Russia. The twump campaign lied about all of them
Twump's Russia connection is no Hoax.

"...investigators have found that Trump and
at least 17 of his campaign officials and advisors had more than 100 contacts between Trump associates and Russians, belying the campaign’s November 2016 claim that “there was no communication between the campaign and any foreign entity during the campaign.” According to reporting, many others associated with Trump were told about contacts with Russian-linked individuals."
