The Supreme Court majority built by Donald Trump could uphold efforts to expand presidential authority based on the legal principle of unitary executive theory.

The president fired inspectors general without providing Congress the legally required notification and list of reasons for dismissal. Some in Trump's orbit have previously said the president should actively confront the judiciary.

Americans should be prepared for the administration to ignore them, “unless and until there's real enforcement, either by law enforcement or by the Supreme Court,” says Ty Cobb, a former White House counsel during Trump’s first administration.

Now the question is whether the court rulings are a mere speed bump or an insurmountable roadblock for the Republican president.
