UPDATED: A split in the House Republican Caucus exploded into the open Wednesday morning, throwing a major tax bill into further jeopardy.
House Republican leaders, led by Speaker Thom Tillis, sought to strip a provision added to the bill a day earlier that added $500 million in cost. But a cadre of Republicans and Democrats joined forces in the Appropriations Committee to block a proposed substitute bill from even being considered.
The move left the House tax overhaul -- the top GOP agenda item this session -- in limbo and the lawmakers bewildered. Committee Chairman Nelson Dollar left the meeting dumbfounded and unable to find the words to explain what happened. Other clumps of Republicans huddled in the corners of the committee room, discussing one of the largest fissures in the Republican Caucus this session.
