President Donald Trump’s vision of a border wall began to take shape Tuesday. Contractors trying to win the bid for the final product started building their prototypes in San Diego.

According to Customs and Border Protection, the prototypes will be finished within 30 days. Lawsuits are in progress, including one by California’s Attorney General, who says the construction would breach environmental laws.

Associated Press correspondent Elliot Spagat joined The Show to talk more about it.

One group that is voicing opposition to the border wall concept is Alliance San Diego. Hiram Soto, the group’s communications director, explained his organization's position.
