Rove and President Bush announce Rove's resignation before leaving for Texas on Monday.
WASHINGTON (CNN) – An emotional Karl Rove characterized his tenure in the White House as a "witness to history" as he announced his resignation as President Bush's senior political adviser at the end of this month.
"It seems the right time to start thinking about the next chapter in our family's life," Rove said, his voice breaking. "It's not been an easy decision."
Speaking to reporters outside the White House with Bush at his side, Rove said discussions about his departure began last summer. "It always seemed there was a better time to leave, somewhere out there in the future. But now is the time."
He told Bush he would be "your fierce and committed advocate on the outside."
