"The Senator and his family are reviewing further treatment options with his Mayo Clinic care team. Treatment options may include a combination of chemotherapy and radiation," the hospital statement said.

The forecast from the Congressional Budget Office on Senate Republicans' latest health care strategy isn't great — but it's no surprise either.

The CBO estimates that legislation that repeals key pillars of the Affordable Care Act (aka "Obamacare") would trim $473 billion off the federal deficit, but result in 32 million fewer insured Americans in the next decade. It would also see premiums rise, and likely force private insurers to abandon the individual market.
