Senate Republicans are adding $45 billion to their ObamaCare replacement bill to fight opioid abuse, according to sources familiar with the discussions.

The move was widely expected as an attempt to win over moderate Republicans like Sens. Rob Portman Robert (Rob) Jones PortmanMcConnell locks down key GOP votes in Supreme Court fight Romney undecided on authorizing subpoenas for GOP Obama-era probes Congress needs to prioritize government digital service delivery MORE (Ohio) and Shelley Moore Capito Shelley Wellons Moore CapitoCongress must finish work on popular conservation bill before time runs out Second GOP senator to quarantine after exposure to coronavirus GOP senator to quarantine after coronavirus exposure MORE (W.Va.), who have both made the opioid epidemic a priority.

But both Portman and Capito have said that their concerns extend beyond opioid money to the deep cuts the legislation would make to Medicaid.

Capito said explicitly earlier this week that more opioid money would not be enough to win her over.

“More opioid funding would be very good and very beneficial, but the core for me is the Medicaid provision,” Capito said.

The change to the bill was first reported by Politico.

Sources say Republicans are also looking to expand the use of health savings accounts in the bill. Those are tax-free accounts people can use for medical expenses and are favored by conservatives. But conservatives have pushed for more than simply an HSA change to win their votes.
