I just google it and found this within a NYT article by UPI.
Quote from that article.
WASHINGTON, Sept. 22 (UPI)—The president is empowered to call Congress back for emergency reasons. But can he send lawmakers home when the legislative mill bogs down?
The answer is yes—but only under, certain unusual circumstances. These conditions are so limited that a President has never exercised the power to adjourn Congress.
The Senate Parliamentarian, Charles Watkins, said today that under the Constitution the President might adjourn Congress “to such time as he shall think proper” in the event the House and Senate were locked on an adjournment date.
Thanks for the information.
Regarding convening, it seems the Constitution is clear and unambiguous that his power is absolute.
Regarding adjourning, the language is not absolute in its power, it is dependent upon what is the meaning of “disagreement” regarding the process and definition of adjournment.
It awaits a Supreme Court decision which I don’t trust with Roberts rewriting the rules as he whims.
I hope he does exercise the adjournment powers.
It is criminal that they can adjourn, but not call it adjournment if just one guy shows up every third day.
