'It's Got So Many Bad Parts': Sen. Warren On House GOP Health Care Bill

Republicans in the U.S. Senate are now hammering away on their vision of a bill to overhaul the Affordable Care Act.

The House passed its version of the American Health Care Act (AHCA) Thursday that would repeal the bill known as Obamacare. The bill was passed after a few hours of debate and without the Congressional Budget Office "scoring" it, meaning without the prediction of how much it would cost or how many people would lose their insurance under it.

One thing the House bill does is it allows states to opt out of requiring insurers to cover people who have pre-existing conditions.

Massachusetts U.S. Sen. Elizabeth Warren joined WBUR's All Things Considered and said that would cause problems for millions of Americans.
