A proposal to make the private University of Pikeville a public institution has hit a roadblock in the Kentucky legislature. House Speaker Greg Stumbo conceded Thursday he doesn't think lawmakers will accept a proposal to use millions of dollars from a tax on coal mined in the region to turn the private University of Pikeville into a public school. What started as a seemingly unlikely proposal had gathered momentum early in the legislative session. But that momentum waned in recent weeks, after local officials and public university leaders objected. Former Gov. Paul Patton, now president of the University of Pikeville, says a compromise is being drafted that would allow a portion of the coal tax revenue to be appropriated for college scholarships for eligible mountain students.
