Several Senate Republicans are arguing for a full-scale repeal of Obamacare along the same lines as the 2015 repeal bill, paving the way for a GOP battle over some aspects of the law. Kentucky Republican Sen. Rand Paul said Tuesday afternoon that he would support a repeal bill that was as complete in its repeal of the health care law as the 2015 version, which passed the House and the Senate but was vetoed by former President Barack Obama. The House Freedom Caucus voted Monday evening to vote for only for an Obamacare repeal bill that’s at least as complete in its overhaul as the 2015 repeal bill.
