The President is not immune to criminal investigation. Huge precedent.
The 5 Conservatives on SCOTUS could’ve ruled that POTUS had absolute immunity, and broke our democracy, but they didn’t. Roberts, Gorsuch, & Kavanaugh ruled with liberals.
I know people are focused on #TrumpTaxes but the big picture is encouraging for our democracy. This precedent ensures future presidents can’t make the same arguments of immunity.
