If you think it is only 2 people, you haven't been paying fucking attention. You have Rex Tillerson, who got the Russian Friendship medal as Exxon CEO, Jared Kushner, Carter Page, Paul Manafort, Jeff Sessions, and Michael Flynn.
You are the one that doesn't understand what is going on. I guarantee, Flynn won't get immunity, he will be lucky he won't be spending time in jail. And the Jared Kushner stuff will probably lead to Trump as well.
