WASHINGTON – It was no accident that President Trump Wednesday retweeted an image of Deputy Attorney General Rod Rosenstein locked up.

When asked during an interview with The Post: “Why do you think he belongs behind bars?” Trump responded: “He should have never picked a Special Counsel.”

Earlier Wednesday, the commander-in-chief retweeted an image of his so-called enemies behind bars that said: “Now that Russian collusion is a proven lie, when do the trials for treason begin?”

Along with Rosenstein, the imprisoned foes include former Presidents Clinton and Obama, Hillary Clinton, James Comey, Loretta Lynch, John Podesta, Huma Abedin, Eric Holder, James Clapper and Special Counsel Robert Mueller.

Rosenstein appointed Mueller in May 2017 after then-Attorney General Jeff Sessions recused himself from the Russia probe.

Trump has repeatedly railed against Mueller’s subsequent “witch hunt.” He also fired Sessions in November.

The president declined to answer a question on whether he intends to fire Rosenstein, but stood by his firing of Comey.

“Thank God I fired Comey,” Trump said. “Because if I didn’t fire Comey, we wouldn’t know about (Andrew) McCabe, we wouldn’t know about (Peter) Strzok and his lover Lisa Page.”

McCabe was the deputy FBI director. Strzok and Page both worked for the FBI. Trump accused all three of opposing him and they’re all now gone.
