Karen Hughes, U.S. President George W. Bush's top aide, announced on Tuesday that she is resigning as White House counselor.
"Later this summer, I'm going to be changing the way in which I serve the president. My husband and I have made a difficult but we think right decision to move our family home back to Texas," Hughes announced in the White House briefing room.
Hughes said she would continue to advise the White House from Texas "on big-picture communication strategies," adding that Bush accepted her decision and respected it.
"The president has asked me -- and I have agreed -- to continue to ... serve as a key advisor to him, to help develop his message, give him advice on strategic communication, and to continue to work on major speeches," she said.
Hughes, 45, has worked for Bush since his days as Texas governor and is one of his closest confidants. She and Bush's political aide Karl Rove were critical to Bush's rise from governor to the presidency.
Hughes explained that she made the decision now because she had a May 1 deadline to decide whether her teenage son would remain in Washington schools. She and her husband wanted their son "to have his roots in Texas" during his last few years of secondary school.
