A House subcommittee will examine the impact of President Obama's health care law on doctors and patients at a hearing on Tuesday.
House Republicans are set to vote this week to overturn the law.
The vote is largely symbolic since it has no chance of passage in the Democrat-controlled Senate. But the vote will put House members on record for the upcoming campaign.
The legislative effort follows the Supreme Court's decision to uphold the law's mandate that individuals buy health insurance or face a penalty.
The White House says it would veto a repeal, citing that it would cost millions of American families the security of affordable health coverage.
