Rep. Al Green (D-TX) told Homeland Security Secretary Markwayne Mullin to "shut up" during a House committee hearing on June 4, 2026 [1].

The incident highlights the intensifying volatility of congressional oversight hearings, where policy debates frequently devolve into personal confrontations between lawmakers and executive officials.

The exchange occurred during a hearing focused on the funding of the Department of Homeland Security [2]. According to reports, the tension peaked when Secretary Mullin asked Rep. Green whether the congressman was calling him a racist [3].

In response to the question, Green said "shut up" [4]. The outburst interrupted the proceedings as the committee discussed the agency's financial requirements and operational budget.

Secretary Mullin had sought clarification on the nature of Green's comments before the representative said for the secretary to stop speaking [5]. The confrontation took place in the presence of other committee members and staff during the formal testimony process.

This interaction is part of a broader trend of high-friction encounters in the U.S. House of Representatives, where funding hearings often serve as venues for political theater rather than strictly fiscal deliberation [2].

“"shut up"”

The clash between Rep. Green and Secretary Mullin reflects the deep ideological divide within the U.S. government, where discussions on funding and security are frequently overshadowed by accusations of racial bias and personal animosity. Such interactions often signal a breakdown in the traditional decorum of congressional oversight, potentially hindering the efficient passage of agency budgets.
