Efforts to boost enrollment and raise awareness of President Obama's healthcare law are the next target for House Republicans.

Republican Sen. John Thune (S.D.) is demanding that the Internal Revenue Service (IRS) refrain from implementing ObamaCare while investigators probe the agency's targeting of conservative groups.

Thune, who leads the Senate Republican Conference, wrote to the Obama administration Tuesday connecting the scandal to Sarah Hall Ingram, an IRS official who once had oversight of tax-exempt groups.

Hall Ingram is now in charge of the IRS's functions under ObamaCare, which include enforcing the law's individual mandate. Thune said the IRS must stop working on any regulations drafted under Hall Ingram's leadership while her role in the Tea Party scandal becomes clear. 

White House press secretary Jay Carney on Tuesday unfavorably compared questions about donations solicited by Health and Human Services Secretary Kathleen Sebelius to Republicans questioning the president's birth certificate.

At a tense briefing where Carney took tough questions on a series of issues that could damage the White House politically, the press secretary aligned himself with White House Communications Director Dan Pfeiffer, who over the weekend accused Republicans of engaging in “partisan fishing expeditions.”

“You know, we could go down the list of questions — we could say, what about the president's birth certificate?" Carney responded. “Was that legitimate?”

A federal appeals court on Tuesday struck down an Arizona law banning most abortions after the 20th week of pregnancy.

A panel of the 9th Circuit Court of Appeals said the Arizona law is unconstitutional, citing an "unbroken stream" of Supreme Court rulings on abortion rights.

Arizona's law banned abortion after 20 weeks except in the case of a "medical emergency."

Congressional Republicans warned Tuesday that the public might not be able to trust the people who will help navigate new coverage options under President Obama's healthcare law.

Republicans questioned whether felons could sign up to help people navigate the healthcare law, then make off with reams of personal information. They also said lax regulations might lead to bad advice.

GOP lawmakers also questioned whether part of the program is being implemented illegally.

Sen. Heller introduced an amendment to the farm bill that would prevent the IRS from receiving funds to implement ObamaCare.

People in the Deep South support expanding Medicaid under President Obama's healthcare law, though they oppose the law itself, according to a new poll.

The survey, released by the liberal advocacy group Families USA, found that 62 percent of respondents had a favorable view of the healthcare law's Medicaid expansion.

The survey polled adults in Alabama, Georgia, Louisiana, Mississippi and South Carolina — deeply conservative states, but places where the Medicaid expansion would cover millions of uninsured people.
