He does not need to simply _claim_, he must certify. And one of those is:

“there are in place the relevant binding legal agreements to enable execution of such qualified divestiture during the period of such extension."

This is a binary thing. No such legal agreement seems to exist. You also ignored the other parts of my comment about him missing the deadline in the law to apply the extension.

Johnson himself said they will enforce the law. https://www.nbcnews.com/politics/congress/speaker-johnson-2-...

"Certify" does not mean the same as prove with evidence. I don't think there's a specific threshold that has to be met there other than the parties agreeing it has been certified. It can even come down to as much as "trust me bro" from the president.

The definition of certify is literally "attest or confirm in a formal statement"

Besides, there's no process through which Congress would question or investigate whether the president really can or cannot certify whatever he claims about this matter.
