WASHINGTON AP – A key senator is examining whether a top Securities and Exchange Commission official gave sensitive information to a former colleague working at JPMorgan Chase & Co. when the bank was considering whether to buy Bear Stearns.

Sen. Charles Grassley of Iowa, the senior Republican on the Senate Finance Committee, has asked the SEC for information concerning its investigations of investment bank Bear Stearns & Cos., which nearly collapsed into bankruptcy in March and was purchased by JPMorgan Chase with a $29 billion federal backstop.
