On the campaign trail, Donald Trump looked Hillary Clinton in the eye and told her point-blank that, if he ran the Justice Department, “you’d be in jail.”

But almost a year into his presidency, Crooked Hillary is still running around scot-free.

Now a key Trump ally is issuing a chilling warning for the president: It’s now or never. He’s got to lock her up or risk losing his presidency – and America, forever.

Roger Stone, a former Nixon administration official with long and close ties to Trump, is outraged that the Justice Department hasn’t investigated the Clinton Foundation’s money laundering, influence peddling, or dozens of other Clinton family crimes.

“This reeks of a cover-up, folks,” Stone said on his show “War Room” this month. “I publicly urge the president to order Attorney General Jeff Sessions to appoint a special counsel, a special prosecutor, to look at Uranium One.”

That scandal alone could put the whole Clinton family behind bars for a long, long time.

As Secretary of State, Hillary signed off on a Russian-owned firm buying 20% of the uranium America had at the time.

Coincidentally, it came right after its investors donated $145 million to the Clinton Foundation, and Bill Clinton earned a cool half-a-million dollars for a speech in Moscow.

“Where I come from, they call that a bribe,” Stone said.

Chelsea Clinton oversaw the foundation at that time, too, and could join her parents in the big house.

Stone said Trump should flip the investigation around and shine a spotlight on the whole corrupt D.C. establishment. “While he’s at it, he can also look at the use of taxpayer funds to pay for the smear document created by…the undercover research operation GPS Fusion,” he said. “It is time for the Trump Justice Department to stop fighting in court against the release of Hilary’s e-mails and adhere to the rule of law.”

Stone told his friend Trump that he’s in a death match with the Deep State, and he needs to kill or be killed.

“It is the president’s very best tactic for survival,” Stone said.

The Deep State has tried to destroy Trump through phony leaks, fake news, and a never-ending probe into alleged “Russian collusion.”

Trump promised to appoint a special prosecutor into the Clinton machine in 2016.

But after he was elected, establishment Republicans told him to back off – that investigating your political opponent made him look petty and “unpresidential.”

Besides, they don’t want Democrats putting them in jail for the crimes they’re concealing. In Washington, corruption is a bipartisan policy.

Trump decided to listen and said the Clintons had “suffered” enough.

Big mistake.

The D.C. Swamp hasn’t cut him any slack, and Hillary’s louder, bolder, and more shameless than ever.

Last weekend, she even called for him to be investigated over decades-old claims of sexual harassment.

Trump’s heart was never in the truce – and it looks like he’s about ready to stop listening to the RINOs and haul the Clinton family downtown.

Trump took to Twitter to demand the Justice Department and FBI investigate how Hillary stole the Democratic presidential primary from Sen. Bernie Sanders:
