Do you really believe that Rudy Guiliani, a man acting as Trump's lackey for numerous things, received bombshell information and publicized it without Trump having any knowledge or involvement?
Michael Cohen testified under oauth that Trump knew about leaked DNC emails in advance of the 2016 election. Fast-forward to ~2019 and Trump had already personally tried to pressure Ukraine into providing damaging information about Joe Biden. There is very little plausible deniability here.

I am obviously not referring to a collective conspiracy of between hundreds of millions of American citizens. I meant the Republican Party.
