Keyword there is PUBLIC. He used the threat of public outcry to get them to step down. Thats not power but you know that. Here it is again:
"
The Federal Reserve operates independently of the U.S. government,
and its monetary policy decisions are not approved by Congress or the U.S. president. This independence helps the Fed operate free of political pressure, but it also
limits the Fed's accountability."
See the part about limiting accountability? The only power move the gov't can make over them is to get rid of the bank as a whole. Ghaddafi tried that though and look what happened to Libya
Holding the gov't accountable to the constitution they claim they instituted is KKK logic?
