Trump never had control of both houses by the way. 2017 he started with a slim margin in the senate that got smaller later in the year.
But the Republican margin in the senate was a myth. The Senate has a nest of RINO rats that betray the country and their voters frequently. Republicans do not vote in-block like the Dems, they are full of traitors willing to destroy the country to enrich themselves.
Let’s be honest, spending restraint was never part of Trump’s platform. He was good at suggesting other countries should pay more though.
He did his first two years. That’s how the tax cuts made it through. But so much more could and should have been done. Yet, Trump and his presidency was under constant attack by many in and outside of congress who wanted him not only gone, but imprisoned.
