With the Mueller statement concerning the Cohen issue?

Could Trump and lawyers be the source of the story to BuzzFeed? It is possible? Rudy and his antics the other night saying that the campaign(ie. Cohen) could have colluded with the Russian. Cohen has a thorn in Trump's side since he has flipped and they are trying make him unreliable and also smearing his name? I thought the story was a little far fetched and we need to see what Mueller's report says. Mueller has not leaked anything about, but may be trying to stay out in front by this? I don't trust Cohen, but if he has the goods on Trump then with bring them to light!
