WASHINGTON (AP) — Treasury Secretary Janet Yellen says she is not predicting when the Federal Reserve may need to start raising interest rates. She was seeking Tuesday to clarify earlier remarks that rattled financial markets. In recorded comments released early Tuesday, Yellen suggested that interest rates may need to rise slightly to keep the economy from overheating. Those remarks sent stock prices down with the declines led by tech stocks. However, asked about the market reaction to the comments later Tuesday Yellen said a rise in interest rates by the Federal Reserve is not something that she is predicting or recommending.
