Karl Rove, President Bush’s senior political adviser, will voluntarily step down from his White House post at the end of the month, senior administration officials said Monday.

Karl Rove was dubbed by President Bush as “the architect.”

“Obviously its big loss to us, said Deputy White House press secretary Dana Perino. “He is a great colleague, good friend and a brilliant mind.”

Perino said Rove “wouldn’t be going if he wasn’t sure this is the right time to be giving more time to his family.”

Rove, who has held a top position in the White House since Bush took office in January 2001, is to stand down on August 31.
