House Republican leaders are forging ahead with plans to hold a vote Wednesday on a full repeal of President Obama's health care law, after launching debate on the repeal measure Tuesday nearly two weeks after the Supreme Court upheld most of the law as constitutional.

Wednesday will mark the chamber's second vote to repeal the Affordable Care Act in full, though this attempt is being given no greater chance of passing the Democratic-controlled Senate. Obama has vowed to veto any such measure, were it to reach his desk.

House Republicans have held 29 other votes aiming to gut specific parts of the law since 2011.

The House Rules Committee on Monday allotted five hours of floor debate for the latest measure. Lawmakers plowed through four and a half hours on Tuesday, with the remaining time set aside for the day of the vote. 

Democrats accused the Republicans of wasting time with a display of political theater instead of focusing attention on helping the economy.
