During his confirmation hearing in June, Bove told senators that U.S. District Judge Dale Ho granted the DOJ's motion to dismiss the Adams case because it "reflected a valid exercise of prosecutorial discretion."
He denied the existence of the DOJ deal with Adams to drop the charges in exchange for the mayor's cooperation with Trump's mass deportation agenda, saying that "the suggestion that there was some kind of quid pro quo was just plain false."
The decision to drop the charges led several prosecutors to resign from the DOJ in protest.
Sen. Cory Booker (D-N.J.), who serves on the Senate Judiciary Committee and condemned Republicans' decision to advance Bove's nomination earlier this month, first received evidence from the third whistleblower, according to the Post. Several other Democrats have also reviewed the evidence, which Booker told the outlet was "significant."
"We have substantial information relevant to the truthfulness of the nominee," Booker said on the Senate floor, calling on Republicans on the committee to review the new evidence.
"Another whistleblower has come forward with evidence that raises serious concerns with Emil Bove's misconduct. Senate Republicans will bear full responsibility for the consequences if they rubber stamp Mr. Bove's nomination."
Lawyers for the anonymous whistleblower told the Post on Tuesday that they had turned over the new information provided by the person to the DOJ inspector general.
Booker was joined by Sen. Adam Schiff (D-Calif.) on Tuesday in calling on the DOJ's inspector general to promptly open an investigation into Bove in light of the latest whistleblower complaint.
"In the event these whistleblower complaints and other reports have not already prompted investigations by your office, we urge you to undertake a thorough review of these disclosures and allegations," said the lawmakers.
Two other whistleblowers have come forward in recent weeks, alleging Bove told DOJ lawyers to ignore court orders that would impede Trump's mass deportation agenda. Former DOJ attorneys and federal and state judges have urged the Senate to oppose his nomination.
Schiff condemned Republicans on the committee for attempting to dismiss the whistleblowers' complaints.
"What will come out next about Bove?" said Schiff. "That's precisely the problem with this disaster of a nominee. And why Senate Republicans are rushing through his nomination. Before more disqualifying information can come out."
Sen. Sheldon Whitehouse (D-R.I.) emphasized that the fight to stop Bove's confirmation "isn't over, even when subservient Senate Republicans ignore another whistleblower and shove this character through their new-low, hide-the-ball Senate confirmation process and onto the bench."
Republicans can afford to lose only three votes for Bove and still confirm him with a tie-breaker vote from Vice President JD Vance. Sens. Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska) are expected to oppose him.
Josh Sorbe, a spokesperson for Sen. Dick Durbin (D-Ill.), the Judiciary Committee's ranking member, said the latest complaint is "another damning indictment of a man who should never be a federal judge."
"Another whistleblower has come forward with evidence that raises serious concerns with Emil Bove's misconduct," said Sorbe. "Senate Republicans will bear full responsibility for the consequences if they rubber stamp Mr. Bove's nomination."
