In 2010, Manchin called for "repairs" of the Affordable Care Act and repeal of the "bad parts of Obamacare." On January 14, 2017, Manchin expressed concern at the strict party-line vote on repealing Obamacare and said he could not, in good conscience, vote to repeal without a new plan in place. He added, however, that he was willing to work with Trump and the GOP to formulate a replacement. In June 2017, Manchin and Bob Casey Jr. of Pennsylvania warned that repealing Obamacare would worsen the opioid crisis. In July 2017, he said that he was one of about ten senators from both parties who had been "working together behind the scenes" to formulate a new health-care program, but that there was otherwise insufficient bipartisanship on the issue.
