Does that extend to an Article 1 classified info?

Can POTUS declass congresses “classified” information or is such subject to separation of powers?

No, it does NOT extend to Article I information. He can't DECLAS material originating within the Congress. They have sole control over that information.

He has absolute authority over Article II (Executive Branch) material provided to the Congress.

This is why classified briefing material is provided to Congress in writing and not in person. This way if a Congresscritter (Adam Schiff for Brains) discloses the info, they will have committed a federal felony and can be arrested for it.

If Schiff for Brains releases classified testimony, it gets legally murky. You'll need a legal beagle for that.

Thanks, Mr. LonePalm. Some things can be taken to the bank. Your facts-stuff always fits the bill.

Thanks!
One last question, if Congress receives classified information from the executive and subsequently places an equal or higher classification on it, can the Executive declassify the original or is it “captured” by the congressional classification?
Schiffty may have played that game is why I wonder.
