First Trump said, "no interactions with Russians and his campaign."  Then Flynn came out as having done so thus Flynn was out.  Then Sessions and so Sessions had to recuse himself.  Then Trump was caught communicating sensitive information to Russians.  Kushner tried to open backchannel communications.  Trump Jr. got caught meeting Russians, which Trump advised to deny ever happened before Jr. pulled the stain and released his emails.
So now Trump is saying none of these matter.  That they're all low-level or peripheral contacts.  As more circumstantial evidence is found, or even major evidence shall we expect Trump to say even if there was collusion he wasn't involved.  After we have more evidence come out that he was involved then it'll be it doesn't matter/its legal?
