Ok, your point is that the medias reported that Mueller had subpoena Trump's bank accounts while he hadn't only the bank accounts of some organizations affiliated to himself, not his own bank account.
1) What does matters is not what the medias reported : what happened matters
2) Wether Mueller is looking into Trump's own bank accounts or on the accounts some companies afilliated to him is not important. The thing is he's looking for something and he's now looking in some bank accounts where he thinks he's gonna find what he's looking for.
If Mueller founds wha he's looking for, wether he founded it on Trump's own account or on some campany's affiliated to him bank account, wether the medias reported this correctly or not, the only thing that will matter is how much what he found will hurt Trump
