Text of letters sent Saturday to House Speaker Dennis Hastert, R-Ill., and President Pro Tempore of the Senate, Robert Byrd, D-W.Va., about the transfer and resumption of presidential power by President Bush: 

Transferring power to Vice President Dick Cheney:

As my staff has previously communicated to you, I will undergo this morning a routine medical procedure requiring sedation. In view of present circumstances, I have determined to transfer temporarily my Constitutional powers and duties to the Vice President during the brief period of the procedure and recovery. 

Accordingly, in accordance with the provisions of Section 3 of the Twenty-Fifth Amendment to the United States Constitution, this letter shall constitute my written declaration that I am unable to discharge the Constitutional powers and duties of the office of President of the United States. Pursuant to Section 3, the Vice President shall discharge those powers and duties as Acting President until I transmit to you a written declaration that I am able to resume the discharge of those powers and duties. 

Resuming power:

In accordance with the provisions of Section 3 of the Twenty-Fifth Amendment to the United States Constitution, this letter shall constitute my written declaration that I am presently able to resume the discharge of the Constitutional powers and duties of the office of President of the United States. With the transmittal of this letter, I am resuming those powers and duties effective immediately.
