One of President Trump’s campaign promises was to build a wall along the border of the United States and Mexico to help curb illegal immigration and cartel violence and drugs which have been plaguing our country for years. The wall is set to kick off in the San Diego border community of Otay Mesa, U.S. Customs and Border Protection confirmed Monday according to the San Diego Union Tribune. Although the construction is beginning with prototypes, there are documents revealing that wall construction will start in San Diego, CA.
