A question I asked in the thread last night that we need to see in this bill. Currently there is money appropriated every year for the Secure Fence Act, $10.4 Billion per year for security of which about $2.5 Billion is for building and maintaining new or current barriers authorized under that.
If this money is replacing the appropriation for building the current various barriers under the Secure Fence Act, this is actually a cut to border security, not adding on to build the wall. If it isn't, this current funding rate would mean we are 20+ years off from having this built. $1 Billion is about what was used to repair about 90 miles last year.
In other words, as possibly predicted, the Great Wall of Trump may end up being taking credit for the Secure Fence Act that has been under construction for half a decade.
