WASHINGTON — The House on Thursday passed a suite of health care bills that tied shoring up the Affordable Care Act to lowering drug prices, as Democrats tried to hold Republicans to their campaign promises to secure coverage for pre-existing medical conditions and rein in the cost of prescription medicine.

But Democratic leaders appeared to be focused less on the substance of the measures than on their likely demise in the Republican-controlled Senate.

“There’s been a relentless campaign of sabotage by the Trump administration to deny people health care, and thankfully, the new Democratic majority in the House has taken action,” Speaker Nancy Pelosi said at a Wednesday news conference to push the legislation. “But the Republican-led Senate? No movement. Nothing.”

By combining the bills to shore up the Affordable Care Act with several bipartisan measures to address high drug prices, Democrats had hoped to lure in some Republican support. But the minority party did not bite, calling the package “a bailout” for the health law and instead introducing a Republican bill that included only the drug-pricing measures, plus an extension of funding for community health centers and the National Health Service Corps.
