If I have a choice between taking the word of the Republican FBI Director and you, I'm afraid your delusion-rich opinion will be rejected.

Donald Trump has not a shred of evidence Trump Tower was wiretapped.  Nothing.  Nada. Zippo. Zilch. The only person to substantiate Trump's claims is a Fox News Analyst who the network refused to support.... oh.... and you... because you have evidence, I'm sure.

On the other hand, the FBI Director did indeed confirm to a Congressional Committee that an FBI investigation into the relationship between Trump's election team and Russian attempts to influence the 2016 Presidential Election is in progress.  That the Russians attempted to influence the election isn't being questioned by anyone.... except you, I suppose.  The only question is whether the Trump Campaign knew about what was happening and were supporting or cooperating with the Russian agents.
