Congress is going to build in rigidity to the USA military budget. That is probably very important regardless of the wall. But, in building in a more rigid budget for the USA military there needs to be a Congressional Ad Hoc Committee composed of members of Congress as well as senior military members. The Ad Hoc Committee should be able to meet for urgent needs and immediate movement for bills before Congress to adjust the budget.
The USA Congress had confidence in the USA military's use of the country's taxes. The manifestation of manipulation by the Executive Branch is an attack on the USA Constitution which separates powers of the government. That should never happen. Congress needs to retake it's status and soon.
The most recent egregious abuse of the Executive Branch is sequestering a two year long investigation to the Russian intrusion on the 2016 elections. It is not appropriate for Congress to be treated as a second class citizen. The Mueller Report needs to proceed to the US Congress for assessment to legislation. The entire idea that an Attorney General can prevent Congress from reading a vital report only leads to greater and greater suspicion to the relationship between Russia and the current Executive Branch.
