The proposed wall along the U.S.-Mexico border could be paid for by reducing erroneously issued tax credits that go to “mostly Mexicans,” said Attorney General Jeff Sessions on Sunday.Speaking on ABC’s "This Week," Sessions weighed in on the fight over funding for the wall, which is becoming part of the high-stakes negotiations between the White House and Congress over keeping the government funded after Friday.“We're going to get paid for it one way or the other,” Sessions said of the wall.
