If I asked you to put together the profile of one person who personified this "Swamp" more than any other, do you know who would be a good place to start?
Paul Manafort.
Read up on the guy. He spent his entire career peddling influence in Washington to foreign interests. Even many of Trump's strongest supporters who have worked in the Beltway for years acknowledge that the guy is a crooked bastard.
Are you suggesting Michael Cohen was NOT a legitimate target of a Federal investigation? The stories about him collecting millions of dollars in "consulting fees" from companies who were promised access to President-Elect Trump are absolutely damning.
