WASHINGTON — As President Donald Trump's top law enforcement officials were firing and forcing out waves of Justice Department veterans, Sen. Chuck Grassley denounced a ''political infection'' that had poisoned FBI leadership.
The Iowa Republican was not criticizing FBI Director Kash Patel or Attorney General Pam Bondi. In a July statement, he directed his ire at the FBI's ''extreme lack of effort'' in investigating Democrat Hillary Clinton's use of a private email server as secretary of state a decade ago.
Trump loyalists have roiled the Justice Department, shattering norms and leading to a mass exodus of veteran officials, but the 92-year-old chairman of the Senate Judiciary Committee has remained focused on the past.
Critics say Grassley's reluctance to challenge the Trump administration has even extended to a defining issue: His support for whistleblowers making claims of fraud, waste and abuse.
In an interview, Grassley insisted he has not abandoned his oversight role. He said he has felt compelled to investigate issues under earlier presidents to avoid a repeat of what he described as politically motivated prosecutions carried out against Trump and his allies.
''Political weaponization is being brought to the surface and being made more transparent because this administration is the most cooperative of any administration — Republican or Democrat,'' Grassley said.
Grassley has acknowledged that Congress has ceded a great deal of power to the current administration, a concession he says makes his own oversight more crucial.
''It's going to enhance the necessity for it,'' he said.
