Welcome to The Daily Politic Briefing! I'm your host bringing you the most crucial political developments of the day. From escalating tensions over congressional security funding to landmark cryptocurrency legislation, we're covering the stories that matter most in Washington and beyond. These are fast-moving stories with significant implications for American politics and policy. Today's briefing covers: lawmakers clashing over security funding after recent violence, Senate Republicans struggling with their tax-and-spending package timeline, the first congressional hearing on President Biden's mental capacity, competing resolutions on the Israel-Iran conflict, a major cryptocurrency bill advancing in Congress, and concerning deficit projections for the GOP megabill. Let's start with the heated debate over congressional security. Following recent political violence, including shootings of state lawmakers in Minnesota, members of Congress are divided on whether to increase funding for their own protection. Top Democrats are advocating for additional resources for Capitol Police and personal security programs, with some Republicans also supporting enhanced measures. Currently, round-the-clock security is limited to select leadership positions, leaving most lawmakers with minimal protection. Despite existing programs for security equipment and home protection, many representatives don't utilize these resources due to privacy concerns or administrative challenges. The Capitol Police budget request for fiscal 2026 stands at $967.8 million—a 22% increase that could soon push security spending beyond $1 billion. Meanwhile, Senate Majority Leader John Thune faces significant hurdles in his push to pass the Republican tax-and-spending package next week. Rank-and-file Republican senators remain divided on several policy issues. The White House is pressing for passage by Independence Day, though Vice President JD Vance has indicated the ultimate deadline could be the August recess. Disagreements center around proposed Medicaid reforms, with hospital executives and moderate Republicans opposing plans to reduce state provider taxes. Additionally, several GOP senators are seeking to soften proposed rollbacks of clean energy credits to provide more transition time for hydrogen and solar power projects. In a particularly contentious development, congressional Republicans are holding their first hearing today on President Biden's alleged mental decline. The panel, co-chaired by Senators Eric Schmitt and John Cornyn, will hear testimony from former Trump administration officials including Sean Spicer and Theo Wold. Notably absent will be any Biden administration representatives. The committee's ranking Democrat, Senator Dick Durbin, plans to deliver an opening statement before immediately departing the hearing, with Senators Adam Schiff and Peter Welch following his example. On the international front, House members are considering competing resolutions regarding the Israel-Iran conflict. Representatives Thomas Massie and Ro Khanna have introduced a privileged war powers resolution aimed at blocking U.S. involvement, while Representatives Brad Sherman and Claudia Tenney have countered with a resolution reaffirming American support for Israel's military actions. In the Senate, Tim Kaine is preparing to force a floor vote on his own privileged resolution barring U.S. involvement in Iran as soon as June 25, though support for the measure remains uncertain. In a significant legislative achievement, the Senate has passed landmark cryptocurrency legislation establishing America's first regulatory framework for stablecoins—representing a major victory for former President Trump and industry advocates. However, the bill faces an uncertain future in the House, where Republicans are considering potential modifications and possibly combining it with broader measures to divide digital asset regulation between market regulators.
