Former Florida Gov. Jeb Bush acknowledges that he's been supportive both of a pathway to citizenship for undocumented immigrants and of a lesser measure granting only legal status, saying his position is underscored by a desire to de-incentivize illegal immigration to the United States.

Bush told CNN's Jake Tapper, anchor of the upcoming show "The Lead", that while his new book "Immigration Wars" specifically says immigrants who came to the U.S. illegally should be barred from a pathway to citizenship, he could support such a pathway if it's proposed by lawmakers this year.
