Noted in “Treasury Secretary Yellen expresses openness to defusing debt ceiling without GOP votes,” Jeff Stein, WaPo:
Yellen has rejected some liberals’ arguments that the administration can resolve the debt ceiling impasse unilaterally.

The administration said last month that those ideas are not actively under consideration.
