Deputy White House press secretary Raj Shah told the Times that Trump has “enormous respect for the thousands of rank-and-file FBI agents who make up the world’s most professional and talented law enforcement agency," but that top officials, including Comey, had tainted the agency's impartiality in pursuing justice.

Trump in June nominated Christopher Wray to replace Comey, who he fired in May. Shah told the paper that Wray is "the right choice to clean up the misconduct at the highest levels of the FBI and give the rank-and-file confidence in their leadership.”

The House Judiciary Committee is reportedly preparing subpoenas for the two agents, Peter Strzok and Lisa Page, who allegedly exchanged the texts during the investigation, as well as McCabe and Justice Department official Bruce Ohr.
