(CNN) — President Barack Obama's sweeping health care law came under fresh assault from Republicans over cost and complexity with a Senate lawmaker saying comprehensive doesn't mean comprehendible.
Speaking the week after the Obama administration said it would delay a key provision of the law, U.S. Sen. Mike Enzi of Wyoming said on Saturday in the weekly GOP address that the Affordable Care Act was a "partisan experiment in government-run health care" that had failed.
Last week, the Treasury Department said it was delaying by one year the requirement that businesses with 50 or more employees provide workers with health insurance -- a provision that had long been contested by Republicans, who said it would hurt jobs growth.
In the weekly address, Enzi predicted the delay would force more Americans to enroll in the health care exchanges created under Obamacare -- thereby increasing costs to taxpayers.
"Where did he find this authority to pick and choose what parts of the law he'll put in place and when?" Enzi wondered. "Republicans and Democrats alike are asking how the administration can possibly justify this decision."
Part of the problem, Enzi argued, was Obamacare's length, which he said made it impossible for any single lawmaker or agency to fully to fully determine the effect of the law.
"After 20,000 pages and still adding new regulations, and over 150 new bureaucratic agencies, boards, and programs, they still haven't figured out what is in the law, or how to make the law work, which is why we need to permanently delay implementation of the law," he said.
Lawmakers in the GOP-controlled House of Representatives have voted numerous times to repeal all or part of Obamacare, though those efforts have stalled in the Senate, which is controlled by Democrats.
In his address, Enzi decried Washington's penchant for passing enormous laws he said don't allow for thoughtful debate. While not specifically mentioning the current push for comprehensive immigration reform, the Wyoming Republican took aim at laws that seek to make sweeping changes.
"We also need to get away from trying to do everything comprehensively," Enzi said. "'Comprehensive' usually means incomprehensible. The larger a bill gets, the harder it is for people to understand and agree. This is especially true when we try to pass bills that no one can have read and we have to find out what's in them after we pass them."
