He says it’d be another vote by the panel to boost the nation’s economic engine.Grassley expects the rate cut to be at least a quarter-point and perhaps a half-point. Grassley says he has faith in Fed chairman Alan Greenspan to do what’s best for the nation.Grassley says he should share some of the credit with Greenspan for helping the economy. Grassley says, “It isn’t just what the Federal Reserve Board does, it’s the tax cut that I got through Congress” which is rebate checks of 65-billion dollars that are helping stimulate the economy as well. The announcement is expected about interest rates about 1:15 p-m central time.
