President Trump addressed questions from reporters Wednesday following a news conference with Norway's Prime Minister. PolitiFact Staff Writer Jon Greenberg fact-checks the comments from politicians surrounding the immigration debate.

One of the big themes in all of the government spending discussions coming up involves Trump's plan for a border wall. The Department of Homeland Security estimates the real cost between $21 and $22 billion. "Frankly until you have a design you don't know," says Greenberg.

Back in July Attorney General Jeff Sessions cited a study by the University of California that found crime was higher in sanctuary cities. PolitiFact rates this statement as mostly false. "The reality is the authors of that study said no, you can't say that because you can't draw strong conclusions," says Greenberg.
