In addition, annual inflation has dipped further below the Fed's annual target level. However, he is likely to keep silent on how deep the rate cut might be.
President Trump has repeatedly argued that the USA economy would be growing faster if the Fed lowered interest rates.
Trump, who is counting on a strong economy for his re-election campaign, has called the Fed his biggest threat. And he must do this all without admitting that the Fed misread the economy when it hiked rates a year ago.
