WASHINGTON (AP) — Two congressional committees are raising questions about what U.S. regulators knew concerning allegations that a key global interest rate was being manipulated.

The chairman of a House Financial Services oversight subcommittee has asked the Federal Reserve Bank of New York to provide transcripts of discussions between Fed officials and the British bank Barclays regarding the setting of interest rates from September 2007 to November 2009. The New York Fed said it would comply with the request.
