Trump: It Is Illegal For Congress to Perform Oversight

Ridiculous as it is as a legal theory, it certainly is world-class trolling:
President Trump sued his own accounting firm and the Democratic chairman of the House Oversight Committee at the same time on Monday — trying an unusual tactic to stop the firm from giving the committee details about Trump’s past financial dealings.
The lawsuit, filed in federal court in the District of Columbia, seeks a court order to block a subpoena issued last week by the committee to Mazars USA.
It amounts to Trump — the leader of the executive branch of government — asking the judicial branch to stop the legislative branch from investigating his past.
To do so, Trump wants the court to negate an idea that has guided Congress for decades: that the legislature’s investigative power isn’t just meant to research possible legislation.
Instead, Congress has used subpoenas to dig into the president’s past and present doings, conducting oversight without a particular bill in mind.
Trump says that’s wrong and must stop.
