Southern Border

Donald Trump pledged to build a wall at the border of Mexico in his election campaign in 2016, but because of opposition from Democrats and the neighboring country, the wall has not been completely built yet.
I read a news article about the border and it said that donations from private individuals and groups keep on pouring in to help achieve their goal.
I was surprised that Trump have a lot of supporters devoting their commitments to serve the President's plans. 
Many of them are worried about the influx of immigrants coming from the border.
I should read articles about this not only from our news articles but also from other foreign medias.
