The U.S.Constitution, Article I, section 3, states that only the Congress has the power to remove a President - NOT the Judiciary.
Lobby congress (with rocks)until they do it.
The judiciary DOES have the power to remove an ineligible usurper. See the Law of Nations for the definition of “Natural Born Citizen” - it doesn’t even matter whether he was born in Hawaii or not - he’s ineligible.
