Sen. Dianne Feinstein, D-Calif., complained Sunday on NBC's "Meet the Press" about the "complicated" House-passed healthcare bill.

"This bill, which looks like this and is complicated to read," Feinstein said, picking up a packet of papers that appeared significantly shorter than the Affordable Care Act, which she supported during the Obama administration.

"I've been trying to read it over the weekend," Feinstein added. "It's probably one of the biggest bills that the Senate will ever consider. We don't know its breadth and depth as analyzed professionally."

Obamacare was more than 2,000 pages long, as House Speaker Paul Ryan noted Sunday on ABC's "This Week."

The revised American Health Care Act was 126 pages with two amendments at 11 pages, making the full bill 137 pages. The Affordable Care Act, combined with a reconciliation bill, totaled 974 pages, in another report.
