re: Barr using the separation of powers to unobstruct lower court rulings

I would like to know how many of these lower court injunctions have been overturned on appeal or by the Supreme Court. I just read where some hack, Obama-appointee, federal judge said that Trump must turn over financial records (that pertain to issues long before Trump was president) to Nadler's committee.

nationwide injunctions issued by lower courts

I took Civics/Government a long time ago in school, but I seem to remember that a ruling by a judge in his district only applied to his district, not the entire country.
