If you close it they will come.
Trump with his talk and his wall is fueling the increase of people willing to make the trip to the border as they believe it maybe there last chance and last hope. It's now or never for many immigrant who see there chance at a better life slipping away.
Trump is doing everything he can to make the problems at the border worse so he can use it as a campaign issue. Cutting funding to countries where these immigrants come from will do what ? Create even more immigrants feeling to this country.
Trump is about creating a problem , then act like he's trying to solve them in a bumbling stupid way that only makes things even worse.
