According to this news report, President George W. Bush endorsed the teaching of intelligent design in schools:
President Bush waded into the debate over evolution and "intelligent design" Monday, saying schools should teach both theories on the creation and complexity of life.
In a wide-ranging question-and-answer session with a small group of reporters, Bush essentially endorsed efforts by Christian conservatives to give intelligent design equal standing with the theory of evolution in the nation's schools. …
Bush compared the current debate to earlier disputes over "creationism," a related view that adheres more closely to biblical explanations. As governor of Texas, Bush said students should be exposed to both creationism and evolution.
On Monday the president said he favors the same approach for intelligent design "so people can understand what the debate is about."
The Kansas Board of Education is considering changes to encourage the teaching of intelligent design in Kansas schools, and Christian conservatives are pushing for similar changes in other school districts across the country.
"I think that part of education is to expose people to different schools of thought," Bush said.
The brief quotations doesn't allow us to determine Bush's position with certainty, but since he compares the situation with the creationist legislation of the 80's, it's a fair interpretation that what he has in mind is to make it mandatory for teachers to teach about ID in a way that makes it appear to be of "equal standing with the theory of evolution".
Two important points must be made: Firstly, Bush doesn't have power over school curricula. In his time, Reagan made his infameous claim that evolution "is a scientific theory only, and it has in recent years been challenged in the world of science", and he never lifted a legislative finger to help the creationists. So, if there are any critics out there worried that this'll be the end of science and that their kids will have ID taught to them, they can relax.
The second important point is that even if Bush had the power to force ID into schools, he shouldn't. ID does not have a scientific theory yet, the purpose of a science education isn't to teach kids about sociological issues ("what the debate is about"), and if you want students to know about "different schools of thought" there are plenty of interesting controversies in biology that don't involve ID.
Bruce Gordon, assistant-director of the now-defunct Polanyi Center, which was founded to research design, put it well:
"Design theory has had considerable difficulty gaining a hearing in academic contexts, as evidenced most recently by the the Polanyi Center affair at Baylor University. One of the principle reasons for this resistance and controversy is not far to seek: design-theoretic research has been hijacked as part of a larger cultural and political movement. In particular, the theory has been prematurely drawn into discussions of public science education where it has no business making an appearance without broad recognition from the scientific community that it is making a worthwhile contribution to our understanding of the natural world."
"Intelligent Design Movement Struggles with Identity Crisis", my emphasis
If intelligent design is ever included on high school science curricula, it should be at the request of the scientific community, not politicians.
