Trump clearly knows that Powell will not listen to him, yet continues to shout from afar. The main reason may be to create an opposition, portraying the Federal Reserve and Powell as hindrances to the risk market, and to highlight the reasons for America's debt. This puts pressure on the Federal Reserve and Powell from a public opinion standpoint, seeking more support from Federal Reserve governors, and creating the illusion in the market that if the economy or the risk market encounters problems, it is all due to Powell not lowering interest rates.
