What % of the stuff on Trump has been leaked?

Are we just seeing the tip of the iceberg and perhaps they are building a pretty devastating case or have we seen the bulk of stuff which leaves him walking the line of impeachment with obstruction of justice? Had there not been leakers we wouldn't know about most of this stuff right now which has me wondering what hasn't been leaked?

I have a strange feeling they may be finding money laundering and racketeering and who knows what with his ties to the Russian mob. Maybe some obvious stuff with Putin where they are blackmailing him.

He acts like someone with something really big to hide. No one with a brain tries to obstruct justice if they don't have anything to hide.
