Protesters campaigned for Trump to build the wall at the southern US border with Mexico and displayed signs such as  Mexicans for Trump,   California for Trump  and  women for Trump. Watch:The organizer of the rally Matthew Woods stressed that Trump supporters are  boycotting many actors and film directors who have an anti-America agenda. A few of the pro-Trump supporters who were present at the rally explained why they supported him: I m Latino and I say,  build that wall.  These illegal immigrants. I actually have a friend whose son was killed by an illegal immigrant. They re losing and it s the price they re going to pay. They re losing support of the arts and the films. We re boycotting many actors and film that have an anti-American agenda, a globalist agenda or an anti-Trump agenda.
