Yields in the Treasury market are rising, threatening to make it more expensive for consumers and the U.S. to manage debt.

In a separate interview on Fox Business Network’s “Mornings with Maria” on Monday, Hassett called U.S. debt “the safest bet on Earth,” but similarly said that the new rating is “backward looking” and is “penalizing us for all the reckless spending of the Biden administration” — all while predicting an economic “liftoff.”
