Welcome to The Daily Politic Briefing! Good day, listeners. I'm your host bringing you the most critical political developments shaping Washington and beyond. Today's political landscape is particularly charged with congressional battles over war powers, budget negotiations, and internal party dynamics that could reshape policy directions for months to come. Today's Top Stories In our lineup today: Congress wrestles with the Iran War Powers Resolution, Senate Republicans face delays on their megabill, House Republicans propose dramatic cuts to government oversight, House Democrats prepare for a leadership vote, Trump targets a Republican congressman, and Jewish organizations advance a security agenda in Washington. Iran War Powers Resolution Creates Congressional Divide The question of presidential authority to conduct military strikes against Iran has ignited a fierce debate in Congress. Speaker Mike Johnson is reportedly considering blocking a resolution from Representatives Thomas Massie and Ro Khanna that would limit U.S. military action in Iran. Meanwhile, the Senate is expected to vote this week on Senator Tim Kaine's resolution requiring congressional approval for any further military action against Iran. The issue has largely divided along partisan lines, with Republicans rallying behind former President Trump's decision to authorize airstrikes, while Democrats question the constitutional basis for these actions. Trump has intensified pressure on Republican dissenters, particularly targeting Representative Massie. Adding fuel to the controversy, Trump recently suggested pursuing "regime change" in Iran, a comment that raised concerns even among some Republican lawmakers. Senate "Megabill" Faces Setbacks and Delays Senate Republicans' ambitious legislative package, nicknamed the "big, beautiful bill," is experiencing significant delays. The Senate parliamentarian has ruled against several key provisions for violating the Byrd rule, including proposed cuts to SNAP spending and the elimination of funding for the Consumer Financial Protection Bureau. Interestingly, a 10-year moratorium on enforcing state and local AI laws unexpectedly survived parliamentary scrutiny. While the full bill text could be released today, floor action is now likely postponed until Thursday. Senate Majority Leader John Thune is reportedly increasing pressure on Republican holdouts, with Trump expected to play a pivotal role in convincing GOP deficit hawks to support the package despite its budgetary implications. House Republicans Target Government Watchdog Funding In a move raising eyebrows across Washington, House Republican appropriators have proposed cutting funding for the Government Accountability Office by nearly half. This represents the latest clash between Republicans and the nonpartisan watchdog agency responsible for investigating government spending and operations. The House Appropriations Legislative Branch Subcommittee is scheduled to mark up this contentious bill soon, setting up what could be a significant battle over government oversight capabilities. House Democrats Prepare for Leadership Test House Democrats' steering committee will vote tonight on who should lead the party on the Oversight Committee. Representative Robert Garcia, at age 47, is viewed as the frontrunner against Representatives Jasmine Crockett, Kweisi Mfume, and Stephen Lynch. This vote will test Democrats' commitment to their traditional seniority system at a time when the party base is increasingly demanding younger, more progressive, and more aggressive leadership. The outcome could signal the direction of the Democratic caucus in the coming years. Trump Launches Campaign Against Republican Congressman In a striking move against a member of his own party, former President Trump's political operation has launched a super PAC called "Kentucky MAGA" explicitly dedicated to defeating Representative Thomas Massie in his next election.
