President Donald Trump unleashed another attack on the Federal Reserve, calling the central bank his "biggest threat," in an interview he gave to Fox Business Network. "My biggest threat is the Fed," Trump said, according to excerpts released by the network ahead of an interview to air at 8 p.m. Eastern. "Because the Fed is raising rates too fast and it's independent so I don't speak to them but I'm not happy with what he's doing because it's going too fast because you looked at the last inflation numbers they are very low." When pointed out to Trump that he nominated Jerome Powell instead of Janet Yellen, the president said he wasn't blaming anyone. "I put him there and maybe it's right maybe it's wrong but I put him there." He also referenced the other nominees to the Fed he's made. "I put a couple of other people there I'm not so happy with too but for the most part I'm very happy with people."
