So the Judiciary could or could not go to congress
and say we believe what the President has done is
unconstitutional and feel that charges should be made?

Then I understand congress passing impeachment proceedings
to the Senate.

[Publius]

Actions leading to impeachment are not the province of the courts because impeachment is a political process, not a legal process. No court would act in this way.

Because sitting presidents cannot be indicted, the most a grand jury could do would be to name the president as an unindicted co-conspirator, which is what a grand jury did to Nixon.
