The AP or the Boston Globe actually calls their report "Bush to try to clarify immigration stance":

In a meeting with members of Congress, President Bush said he needs to do a better job explaining his position on immigration changes, House Majority Leader Tom DeLay said Wednesday.

"He admitted he hasn't done a very good job in being clear to the American people where he's coming from, and he's going to try to do better," said DeLay, who attended the White House session where the president discussed his legislative agenda.

According to a spokesman, Bush's immigration ideas haven't changed, he just needs to explain them better. In related news, experts predict that Bush's popularity could reach single digits sometime in the news few weeks.
