WASHINGTON (Reuters) - U.S. Representative Mark Meadows, chairman of the conservative House Freedom Caucus, said on Wednesday he is very encouraged by the negotiations with Republican leadership over a sweeping healthcare bill. “I’m very encouraged that we might be seeing some real headway,” Meadows told reporters before a caucus meeting. Earlier, a Freedom Caucus aide said more than 25 members of the group opposed the legislation to replace Obamacare, enough votes to sink the bill in Thursday’s scheduled vote.
