Defense Secretary Pete Hegseth is facing criticism on two fronts in Congress, with lawmakers from both parties questioning his recent decisions on Pentagon leadership and personnel policy. During a Senate hearing disrupted by anti-war demonstrators, Republican Senator Susan Collins voiced strong concern over Hegseth's removal of more than two dozen senior military officers since taking office, describing the dismissals as a troubling shift in institutional norms.

Separately, Senate Democrats have challenged Hegseth's newly announced testosterone screening policy for service members, demanding a detailed justification and specifics on how it would be implemented. Together, the two lines of criticism illustrate broader unease in Congress over the scale and rationale of the Pentagon's recent leadership changes and personnel policies under Hegseth.
