President?s Trump?s multibillion dollar project to build a wall along the U.S.-Mexico border is moving full steam ahead. The Department of Homeland Security is now accepting proposals from contractors. This project is so unpopular in California that some cities say they'll bar companies from city contracts if they help build the wall and the state is considering divesting its employee pension fund from these businesses. But hundreds of vendors - many in California - are still trying to get in on what could be a financial bonanza.
