My bet is on it never getting completed. It’s going to be a running grift over the next few years. There will be delay after delay after delay with multiple “independent” contractors rolling through to deal with whatever the current delay is. Those contractors will be chosen via a competitive bid process,. The company bidding the highest kickbacks to Trump being awarded the contract. At the end of the Trump administration, anything actually constructed on the grounds will need to be torn down due to engineering failures, and multitudes of bugs planted by foreign spy agencies.
