Paul Ingrassia's Senate support has significantly declined due to leaked derogatory comments about Martin Luther King Jr. Day and text messages where he allegedly described himself as having a 'Nazi streak.' Both Republican and Democratic senators, including prominent figures such as Rick Scott, Ron Johnson, and Chuck Schumer, have publicly criticized Ingrassia, leading to calls for his withdrawal and Senate Majority Leader Thune indicating the nomination may be pulled.

As reported, Ingrassia's nomination is facing collapsing support in the Senate, with increasing calls—including from within his own party—for him to withdraw. Senate Majority Leader Thune has signaled that a withdrawal of the nomination is possible due to the lack of bipartisan support.

Ingrassia's attorney has questioned the authenticity and intent of some of the controversial texts, while also denying unrelated sexual harassment allegations. The attorney has further asserted that Ingrassia continues to receive support from the Jewish community.

President Trump nominated Paul Ingrassia for the Office of Special Counsel, but there is no indication in the provided information that Trump has publicly commented on the recent controversies or the collapsing Senate support for Ingrassia's nomination.

While not directly addressed in the provided summary, it is standard Senate practice for a president to withdraw a nominee if it becomes clear they lack the necessary support for confirmation, often following public or bipartisan opposition. The president may also be pressured by party leadership to withdraw the nomination to avoid a damaging public vote.
