There's a possibility that the report says he would recommend an indictment for Trump, once Trump is out of office.

Federal prosecutors in the southern district of New York are still doing their own investigation of matters that have nothing to do with Russia.

New York State attorney general is still doing some investigations of the Trump organization in the Trump foundation.

And then of course US House of Representatives seems to be investigating the same things that Mueller investigated. if the mueller report says something like "the only reason we are not indicting Trump is because he is president" the House is definitely going to want to read about that and discuss it further. But it's unlikely the report says something that direct.
