Is Trump right to pressure Jerome Powell to cut the Federal Funds Rate?
I don't think it really matters. This whole thing looks more like a political fight between parties with conflicting interests. The rates won't change much. But right now since Trump has managed to force the Arab dictator to increase production and lower the oil price, his speculation is inflation coming down so he is pushing for lower rates to battle the recession.
Trump likes to control everything and likes everyone to bend the knee. If you prove too stubborn, you will either be sanctioned, tariffed or blackmailed.
That's because he is a psychopath, which I believe is the reason why he has raped little girls in the past. It is not just pedophilia with him, it is his need to feel dominant. Something we can see in all his behaviors (the main reason why I use the term "emperor wannabe" for him).
threatened regarding the Fed's building renovation fund,
He has already cut the funding for far more important stuff like universities budgets just because students were protesting against him...
