Sen. Jim DeMint introduced legislation, with 35 GOP co-sponsors, to finish what the House started: repeal Democrats' reform law.

Repealing the healthcare reform law would cause “needless economic harm,” a group of 272 academics wrote to influential House panels on Wednesday.

Further, repeal would “set back efforts to create a more disciplined and more effective health care system,” wrote the group, which includes several Nobel laureates, former members of the Council of Economic Advisors and former Congressional Budget Office Chief Alice Rivlin.

“Rather than undermining health reform, Congress needs to make the Affordable Care Act as successful as it can be,” the letter reads.

Arranged by the liberal Center for American Progress, the letter was sent to the House Ways and Means Committee and the Budget Committee before they opened hearings on the reform law Wednesday morning. The letter also comes a week after the American Action Forum (AAF) wrote a letter, signed by hundreds of conservative scholars, arguing against the reform law.

“We believe the [law] is a threat to U.S. businesses and will place a crushing debt burden on future generations of Americans,” the AAF letter read.

A day after President Obama urged lawmakers to consider improvements to the healthcare reform law, one of his top economic advisers provided little insight into what improvements the administration would recommend.

In his State of the Union address last night, Obama reiterated his support for repealing the so-called 1099 IRS filing requirement for small businesses and endorsed reforming medical liability laws.

Chairman of the Council for Economic Advisers Austan Goolsbee, pressed by Republicans on the House Ways and Means Committee on Wednesday morning, did not offer specific areas of the reform law the administration would like to see improved.

“I would say that the president’s open to working with you if you identify other items,” Goolsbee said.

The hearing marked a start in House Republicans’ plan to shine a spotlight on a law they believe is deeply flawed. Pointing to the 1099 provision, Chairman Dave Camp (R-Mich.) said it was worth probing the bill further.

A House Republican introduced a bill Tuesday that seeks to weaken the healthcare reform law's requirement for individuals to purchase insurance.

The bill, introduced Tuesday by Rep. Cathy McMorris Rodgers (R-Wash.), would prevent the Treasury Department from hiring new employees to enforce the so-called individual mandate.

The individual mandate doesn't kick in until 2014, and the provision, considered central to the law's success, is facing several challenges in federal court.

Sen. Robert Menendez (D-N.J.) said, “I’m all for weeding out frivolous lawsuits but how you do that is incredibly important.”

Budget Committee Chairman Paul Ryan (R-Wis.), delivering the Republican response to the State of the Union, will say the healthcare reform law “is driving the explosive growth” of the nation’s debt.

Ryan, considered a rising star in the GOP, says the reform law is causing healthcare costs and insurance premiums to rise, and it will force millions to lose the coverage they already have, according to text of his speech sent to reporters before the State of the Union address.

Ryan reiterates GOP plans to replace the reform law with “fiscally responsible, patient-centered reforms that actually reduce costs and expand coverage.”

Citing a recent presidential order to review federal regulations, Ryan said the reform law should be front and center in those efforts.

“The President mentioned the need for regulatory reform to ease the burden on American businesses," Ryan said. "We agree – and we think his health care law would be a great place to start."

In his speech, Ryan takes issue with waivers for reform law requirements that have been granted to more than 200 groups.

“Washington should not be in the business of picking winners and losers,” he said.

President Obama's State of the Union speech is already causing consternation among trial lawyers, half an hour before he even delivers it.

According to his remarks as prepared for delivery, Obama will throw a bone to Republicans by vowing to take up medical malpractice reform. For the GOP, that usually means a $250,000 cap on non-economic damages and other restrictions, as spelled out in legislation introduced this week by Reps. Phil Gingrey (R-Ga.) and David Scott (D-Ga.).

"I'm willing to look at other ideas to bring down costs," Obama is scheduled to say, "including one that Republicans suggested last year: medical malpractice reform to rein in frivolous lawsuits."

Speaking in the same chamber that rebuked the healthcare reform law a week earlier, President Obama in the State of the Union address will reject Republican repeal efforts but embrace the GOP’s call for medical malpractice reform.

In a speech centering on moving forward, Obama will say he is “eager” to discuss ways to improve the reform law, but reject Republican plans to scrap the healthcare overhaul enacted less than a year ago.

“As we speak, this law is making prescription drugs cheaper for seniors and giving uninsured students a chance to stay on their parents' coverage” Obama will say, according to official remarks sent to reporters an hour before the speech. “So instead of re-fighting the battles of the last two years, let's fix what needs fixing and move forward.”

Saying “anything can be improved,” Obama will signal a willingness to work with Republicans to improve the reform, and he will even back medical liability reform, a highly partisan issue that was left out of the sweeping reform bill. Republicans this week unveiled a comprehensive tort reform bill, which Democrats have historically opposed.

Citing the bipartisan Fiscal Commission, which identified healthcare spending as the biggest threat to the nation’s deficit, Obama says lawmakers must find ways to further reduce healthcare costs. The reform law, Obama says, will help tackle costs in programs like Medicare and Medicaid.

President Obama is a few hours away from delivering his first State of the Union address to a Congress controlled in part by Republicans.

We'll be closely watching the address for what Obama says about healthcare reform less than a week after House Republicans voted for a repeal. The speech gives Obama his most visible chance to defend the reform law since the repeal vote, and whatever he says about healthcare could set the tone for Democratic lawmakers going forward.
