Republican leaders are pressing to finalize the domestic-policy megabill by the symbolic July 4 deadline, but internal conflicts and political uncertainties are casting doubt on the timeline. The bill, which includes major tax cuts and fiscal policies affecting the U.S. economy, faces resistance from key lawmakers who are wary of its long-term impacts. Senate Majority Leader John Thune and House Speaker Mike Johnson have maintained confidence, but fiscal hawks like Rand Paul and members of the Freedom Caucus are pushing for deeper spending cuts, complicating negotiations. Meanwhile, several mid-term candidates, including Thom Tillis and Susan Collins, are resisting provisions that could jeopardize their re-election prospects. The outcome of these internal debates could have significant financial and political implications for the bill.
