Regarding the debt ceiling:

You see 2 types of debt, to the public and intragovernmental holdings.
Intragovernmental holdings is money the government has collected from revenue programs that take in more money than they spend, so it's money owned to the USA government itsself and is a pretty useless metric.
Simple example: Social security collects 100b in taxes but only pays out 80b. What do they do with the remaining 20b? Buy US certificates so the money ends up in the general fund! Obviously this doesn't really make sense from a "how much debt does a country have"-level, because you can't be in debt to yourself. It's an exercise done for transparency I'm guessing.
As you can see in the table posted in the link above, debt owned by the public did actually decrease during Trump's administration... with $100 million. The rest of the decrease is a result of a decrease in intragovernmental holdings which isn't real debt. You can make a whole bunch of arguments why the intragovernmental holding debt is important and that is fine, but it isn't debt if you are talking about the outstanding US government debt.
