I don't think "All of them and everything" is really a serious attempt at a response. But a non-serious question demands an unserious answer! Trump hasn't been impeached this time round, for example, so that is check and balance that is being adhered to. And he gave the State of the Union speech which is an action unambiguously in line with the constitution. So there you go, there are checks that are holding and actions taken that are constitutional.
