Background

David McCormick has served as the junior Republican Senator from Pennsylvania since January 2025, having defeated Democratic incumbent Bob Casey in the November 2024 election. A former Army Ranger, hedge fund CEO (Bridgewater Associates), and Deputy National Security Advisor, McCormick brings a national security background to the Senate.

He did not vote on the fifth War Powers Resolution (WPR) motion of 22 April 2026, which the Senate rejected 51-46 in the tightest margin of the Iran war. His absence, alongside Senators Chuck Grassley and Mark Warner, is notable given his military and national security credentials. McCormick has not publicly taken a position on the AUMF question.

The absence of a Republican senator with his profile from the WPR vote complicates reading the vote as a clean partisan signal. As the Iran accountability debate moves toward the 1 May WPR Deadline, McCormick's position on the AUMF Murkowski is drafting will be an indicator of whether his national security background pulls him toward demanding executive accountability.
