By wall, you mean fence. Read the bill.
It is in there. Search for border in the doc. Brings up a couple dozen results and you will find that section.
Not a wall, a fence.
The part not being discussed is that there are more miles of fence being repaired than new miles of fence being built, but I'm just a shill for expecting that campaign promise to be fulfilled.
I've read the bill, we got snowed on the wall (there is zero funding for a wall, only a fence) . Read the bill page starting at page 573 if my memory is correct and please come back and post what you find.
