Which law did he break specifically ?

What he violated is a Constitutional principle, which is bigger than any one law.

He did NOT violate a constitutional "principle" even.

He violated a recent judicial interpretation of an amendment that had been interpreted 180 degrees different just 60 years ago.

America's full of old courthouses with the 10 commandments on them, to include the US Supreme Court. These same bonehead judges will rule and "old" display OK, BECAUSE it historical (hysterical...LOL!), but a "new" display is BAD, presumably because it violates their muse.
