(CNN) House Democrats are taking their first steps to fulfill their promises to strengthen Obamacare and lower drug prices, as the fate of the Affordable Care Act promises to be a major 2020 election issue.

After a marathon session Wednesday, the House Energy and Commerce Committee passed a dozen bills aimed at undoing several of the Trump administration's efforts to weaken Obamacare and at bringing generic drugs to the market faster.

"We were able to move forward in a bipartisan way on bills that will help bring generic drugs to market faster, which will make medications more affordable," said Committee Chairman Frank Pallone, D-New Jersey.

The vote comes after a topsy-turvy two weeks for the landmark health care law. The Trump administration said early last week that it agrees with the ruling of a federal judge in Texas that invalidated the law . President Donald Trump then briefly renewed his quest to repeal and replace Obamacare, before being shut down by Senate Majority Leader Mitch McConnell, R-Kentucky, and declaring there would be a GOP health care effort after the 2020 election.

The health care bills approved this week steered clear of the more controversial measures that Democrats are batting about, including "Medicare for All," allowing Medicare to negotiate drug prices and permitting drug importation from Canada.
