Manhattan District Attorney and longtime rival to Trump, Cy Vance Jr. announced he will not run for a fourth term next year. Vance first came onto Trump’s reader when the Democrat began requesting the president’s tax returns. Recently, the Supreme Court rejected Trump’s plea to block the taxes from Vance.

Fox News reports:

“When I ran for this job in 2009, I said that a District Attorney’s responsibilities should extend beyond obtaining convictions in court, and that a 21st century prosecutor’s mandate is to move our justice system and our community forward,” Vance, 66, said in a statement on Friday.

Vance’s office also touted Trump v. Vance, in which the Supreme Court ruled that Trump was not immune to a subpoena from Vance over his financial and tax records, and People v. Weinstein, which led to the downfall of entertainment mogul Harvey Weinstein.

“I never imagined myself as District Attorney for decades like my predecessors,” Vance said in a statement. “I never thought of this as my last job, even though it’s the best job and biggest honor I’ll ever have. I said twelve years ago that change is fundamentally good and necessary for any institution. Having secured these lasting impacts in our communities, our public policy, and our crimefighting capacity­­, the time has come to open the pathway for new leadership at the Manhattan D.A.’s Office.”

Vance is a Democrat, and the race to replace him is already shaping up to be about radical change as candidates embrace substantial sentencing reform, promise not to prosecute a host of low-level offenses and introduce plans for “decarceration.”

Trump has continually railed against Vance and his investigation into his tax returns saying it’s a “continuation of the greatest political witch hunt in history.”
