The wall is actually being built right now and immigration has slowed to a stop.
"On December 17, 2019, acting Commissioner of U.S. Customs and Border Protection Mark Morgan stated that 93 miles of barriers has been built during the Trump administration; according to CBP figures, at least 90 miles of that replaced existing structures. A private organization called We Build the Wall has constructed 0.5 miles (0.80 km) of new wall on private property near El Paso, Texas, with Trump's encouragement."
In September 2019, Trump said he planned to build 450–500 miles of new wall by the end of 2020.
3 miles of new wall was built as of last December. The patriots that raised non-taxpayer funds built 1/2 mile of new wall on their own.
The US under Trump has promised Israel $38 billion for their security. $38,000,000,000 could fund the US wall.
There are reports of a 7% drop in legal immigration which is a drop in the bucket. There are currently legal immigration restrictions because of Covid but it's temporary.
I understand "trust the plan" and all that but there are prominent always-Trump people on the right(Malkin, Coulter,... ) that are saying Trump has to do more than say the right things. I supported Trump's anti-globalism when never-Trumpers Ben Shapiro, Steven Crowder, Lindsey Graham, Cruz, etc..... were all against him.
If he ends up doing what he said he'll do, I'm all for that.
