The legislature sets laws. The senate approves laws. The judiciary interprets laws.
If the legislature doesn’t like how a law is interpreted, they can change the wording to be less ambiguous, but it would still need to be approved by the senate. This new law would supersede any precedents.
The executive is there to keep the system functioning, not to create any laws itself.
The currently executive in the US is either completely incompetent or maliciously trying to destroy the US.
