That's not your reasoning, though. He doesn't mention SCOTUS there or its change in composition. If he thinks using executive power to forgive debt is questionable now, why did he support it earlier?

He explicitly promised to forgive debt via executive authority back in April. If that actually was not possible, he should not have made that promise, regardless of his political rationale.

Are you actually reading my posts, or just downvoting blindly?

In June, the expectation was a 5-4 SCOTUS and robust Democratic majorities in both the House and the Senate. In that situation, it's very possible to test executive authority for debt cancellation. There'd be a decent chance Roberts would vote with the four liberal Justices to uphold the order, and even if SCOTUS struck down the EO, the Democratic Congress would act swiftly to pass a legislative fix.

We are in a completely different world now and Biden and his advisers recognize that. We don't have a 5-4 SCOTUS anymore, we have a 6-3 SCOTUS. We will have, at best, a 50/50 Senate. This is not a situation where Biden should be testing the bounds of executive authority.
