Perino says Hagin's last day will be July 20th.
"The President said that he thanks Joe for his service to the White House, that Joe's been a loyal friend, and that he is excited about the next chapter in Joe's life," said Perino.
Hagin sent an email to friends this morning, announcing he is leaving to take a private sector job.
Hagin, an Ohio native, has been with President Bush since the 2000 campaign.
Combined with experience during the first Bush presidency, Hagin has served 14 years in the White House.
Hagin was a behind-the-scenes player, who had a huge role in the post 9/11 reorganization of the U-S government and how terrorist responses would be reformed.
