"Some generals thinks this is more important," Trump said of funding a wall rather than military construction projects.

The funding would come at the expense of canceling or leaving half-built a number of DoD projects.

Trump said he was prepared to back a 3-year extension of protection for 700,000 immigrants who came to the U.S. illegally.
