Could U.S. Attorney John Durham’s investigation into the intelligence and law enforcement communities’ handling of the Russia probe be an ‘ace in the hole’ for the president’s fight against impeachment?

Durham, the U.S. attorney from Connecticut, was appointed by Attorney General Bill Barr to make sure intelligence activities information collected by the government were “lawful and appropriate.”

The probe is soon expected to concentrate on the roles of key Obama administration intelligence officials like John Brennan and James Clapper.

“If the rumors are true that IG Horowitz’s report and findings in Durham’s review will blast the conduct of the FBI’s Russia investigation, it will give Trump a lot of ammo to support his argument that he was unjustly targeted then and is being unjustly targeted now,” a House GOP source told Fox News on Tuesday. “It will justify Trump’s warnings about the Deep State acting to hobble his presidency.”

“As soon as Horowitz is done with his review of the FISA warrant application, the counterintelligence investigation, the Trump campaign, we’ll have a hearing in public with Horowitz, and we’ll call a bunch of witnesses,” Senate Judiciary Committee Chairman Lindsey Graham (R-S.C.), said on Fox Business Network’s “Sunday Morning Futures.”

The president has the authority to declassify and release as much of the report as he wants to the American people.

“I predict you will see things that you don’t even believe, the level of corruption—whether it’s [James] Comey; whether it’s [Peter] Strzok and his lover, [Lisa] Page; whether it’s so many other people—[Andrew] McCabe; whether it’s President Obama himself,” President Trump told reporters last week.

One senior Republican aide told Fox News on Tuesday, “Democrats are afraid that the reports will validate what the president has been saying for years—his enemies in Congress are so desperate to undo the results of the 2016 election that they will manufacture conspiracies and sell them to the American people.”

President Trump sparked outrage among the Democrats on Tuesday with his remark that the impeachment push amounted to a “lynching.”

“So some day, if a Democrat becomes President and the Republicans win the House, even by a tiny margin, they can impeach the President, without due process or fairness or any legal rights,” he wrote on Twitter. “All Republicans must remember what they are witnessing here—a lynching. But we will WIN!”
