White House (AP) -- President Bush has invoked executive privilege to deny requests by Congress for testimony from two former aides in connection with the firings of federal prosecutors.
However, the White House has again offered to make former counsel Harriet Miers and one-time political director Sara Taylor available for private, off-the-record interviews.
In a letter to the heads of the House and Senate Judiciary committees, White House counsel Fred Fielding insisted that the president was acting in good faith. Fielding also refused demands from lawmakers that the president explain the basis for invoking the privilege.
Vermont Senator Patrick Leahy says Taylor may testify as scheduled before the Senate panel on Wednesday. Congressional aides say the House Judiciary Committee has scheduled Miers' testimony for Thursday, but it is unclear whether she will appear.
