> if congress is investigating a 'crime' then it is overreach because that is not the responsibility of congress.

If a crime was committed by the US Executive branch (e.g., President, e.g., Nixon), should the Executive branch investigate itself?

Congress investigating things goes back a few centuries:

> On November 4, 1791, some 900 U.S. army troops under the command of Gen. Arthur St. Clair, a Revolutionary War veteran, were killed or wounded in a surprise attack by Native American warriors on the Ohio frontier. The following year, in what was the new nation’s first congressional investigation, a House committee was formed to look into the debacle, which became known as St. Clair’s Defeat. As part of the investigation, the committee asked President George Washington for paperwork pertaining to his administration’s management of the failed expedition.
