During a House Appropriations Homeland Security Subcommittee hearing on June 25, 2026, U.S.Secretary of Homeland Security Markwayne Mullin became involved in a heated confrontation with Rep.Rosa DeLauro (D-CT).

The exchange escalated when DeLauro raised the issue of former President Donald Trump's family separation policy, which separated approximately 3,900 children from their parents at the U.S.-Mexico border.

Mullin interrupted, countering that 450,000 children were reportedly 'lost' during the Biden administration and accusing DeLauro of hypocrisy for not addressing that issue earlier.Mullin, a former U.S.senator and professional MMA fighter, directly told DeLauro she should be 'put in her place.' The hearing chairman, Rep.Mark Amodei (R-NV), had to intervene by banging his gavel to restore order.DeLauro demanded the chairman maintain decorum and refused to yield her time, continuing to press her points on immigration policy.Mullin did not apologize for his remarks.The incident highlights ongoing partisan tensions surrounding border security and immigration enforcement policies from previous administrations.This confrontation occurred amid broader discussions on homeland security funding and oversight.

Such heated moments in congressional hearings underscore the deep divisions in Washington over immigration matters, with both sides accusing the other of inconsistent standards and politicizing sensitive family issues.The event was captured on video and has drawn attention to the tone of political discourse in committee settings.
