… is an individual giving a campaign 2,700$ is considered the same thing as a campaign giving an individual 2,700$?
No. However that's probably not the political nor legal issue here, both of which are more complex, intertwined and subjective. To help think about that (but not answer subjectively): It seems that Cohen has foot-shot himself into jail, hefty fines, and probably disbarment; is he now credible?
If Cohen gave the money to Clifford, the question becomes did he contribute money to the campaign? (Apparently Cohen has plead guilty to campaign finance violation, but I haven't found the details.) Did he do this to seek leniency for his other admitted crimes? Is he now credible?
If Cohen (a lawyer) did this in blind obedience to his unsubstantiated claim that Trump ordered him to do so, who's to blame. As a lawyer did he have a professional responsibility to say "no"? Is he now credible?
Again, based on the fiduciary responsibilities of a lawyer, is he permitted to testify or otherwise speak out against his client by making allegations about a privileged communications? Is he now credible?
These questions may have different legal and political answers depending on who is asked. However neither Trump nor the prosecutors have much good to say about Cohen.
AFIK Nothing says campains can't expend more than $2,700 at a time, it happens frequently. As far as I know its also not illegal for a candidate to contribute more to his own campaign, but there may be reporting requirements involved.
There are probably more difficult questions, these serve simply to show why the reporting is so unclear. I'm not asserting any of them can be answered unbiasedly. But that doesn't stop partisan people from claiming they have the answer.
