Washington, May 14 (AP) President Donald Trump and Republicans are launching a broad election-year attack on the foundation of the Russia investigation, including declassifying intelligence information to try to place senior Obama administration officials under scrutiny for routine actions.

The effort has been aided by a Justice Department decision to dismiss its prosecution of former Trump administration national security adviser Michael Flynn, an action that rewrites the narrative of the 3-year-old case in a way that former federal law enforcement officials say downplays the legitimate national security concerns they believe Flynn's actions raised and the consequences of the lies he pleaded guilty to telling.

The DOJ decision comes as Trump and his Republican allies push to reframe the Russia investigation as a “deep state” plot to sabotage his administration, setting the stage for a fresh onslaught of attacks on past and present Democratic officials and law enforcement leaders.

“His goal is that by the end of this, you're just not really sure what happened and at some gut level enough Americans say, 'It's kind of messy,'” said Princeton University historian Julian Zelizer.

The latest indication of that came Wednesday when two Republican critics of the Russia investigation, Sens. Chuck Grassley of Iowa and Ron Johnson of Wisconsin, disclosed a list of names of Obama administration officials who they say may have received Flynn's identity from intelligence reports in 2016 and 2017.

Among the names is Trump's Democratic opponent, Joe Biden, who was vice president when the Russia probe began.

Names of Americans are routinely hidden, or minimized, in intelligence reports describing surveillance of foreigners, so U.S. officials have to make a specific request if they want to know the person's identity, or “unmask” them.

Biden and the other officials had full authority to seek the name of a unidentified person who had interacted with the Russian ambassador — it turned out to be Flynn.

They did so through proper channels, according to Trump administration documents. Rather than reveal any actual wrongdoing, the release of the information by the president's allies seems designed to create suspicion around Biden and other senior Democrats as the November election approaches.

Trump hyped the disclosure of the list with Biden's name as a “massive thing.”

But the Biden campaign dismissed the revelation, with spokesman Andrew Bates saying it simply indicates “the breadth and depth of concern across the American government” at the time about Flynn's conversations with foreign representatives.

In 2016 the FBI and other agencies were scrutinizing Russian interference on Trump's behalf and trying to understand whether Trump associates were involved in that effort. None of the officials could have known the unidentified person was Flynn, Bates said.

The issue has been politically charged since early 2017, when details emerged about Flynn's conversations during the presidential transition period with Russia's then-U.S. ambassador.

As part of special counsel Robert Mueller's Russia investigation, Flynn pleased guilty to lying to the FBI about having discussed sanctions with the diplomat.

U.S. intelligence agencies who conduct surveillance of foreigners hide or "mask" as a matter of course the names of Americans to whom foreigners speak or speak about in intelligence reports that are disseminated across government.

U.S. officials may ask the National Security Agency to disclose — or unmask — the names of Americans referenced in intelligence reports if they believe the identity is essential in understanding the intelligence, and they do so thousands of times a year.

In fact, unmasking requests increased in the first years of the Trump administration from 2015-2016 totals during the latter years of the Obama administration, according to a government transparency report issued last month.

The list declassified by Richard Grenell, a Trump loyalist and acting national intelligence director, shows a broad range of U.S. officials submitted requests between November 8, 2016, and January 31, 2017, to unmask the identity of the American who was revealed to be Flynn, according to a cover letter from NSA Director Paul Nakasone. It is unclear if they actually viewed the unmasked information.

Flynn's call with Russian Ambassador Sergey Kislyak occurred in late December 2016. Many of the requests to unmask his identity took place before then. The content of the intelligence reports was not disclosed.

The highly unusual disclosure comes as Trump, scrambling to manage the coronavirus crisis, has been eager to shift the focus elsewhere.

He has repeatedly pronounced Flynn “exonerated” and pushed a loosely defined “Obamagate” allegation that the previous administration tried to undermine him during the presidential transition.

Trump has tried to rally his supporters around the claim to revive enthusiasm among voters disappointed by his handling of the pandemic.

He used the first 20 minutes of a recent Fox News interview to attack the Obama administration rather than offer updates on the pandemic.

He has increasingly lashed out in the year since Mueller's report, which while identifying substantial contacts between his associates and Russia did not accuse him of a crime or allege a criminal conspiracy between his campaign and the Kremlin.

Revelations since then have exposed problems in the early days of the FBI's probe, including errors and omissions in applications to surveil an ex-Trump campaign adviser.

Attorney General William Barr has said dropping the case against Flynn, who pleaded guilty to lying to the FBI about having discussed sanctions with the Russian ambassador during the presidential transition, was in the interests of justice.

The department says the FBI had insufficient grounds for interviewing Flynn about his “entirely appropriate” calls and that any imperfect statements he made weren't material to the broader counterintelligence investigation into the Trump campaign.

But the decision stunned former law enforcement officials involved in the case, including some who say the Justice Department is rewriting history and omitting key context.

Former FBI Deputy Director Andrew McCabe said the FBI was obligated to interview Flynn about his conversations with the Russian ambassador, and said Flynn's lies compounded the bureau's concerns.

And because White House officials were inaccurately asserting that Flynn had never discussed sanctions with Kislyak, U.S. officials were concerned Flynn could be vulnerable to blackmail since Russia also knew what was discussed.

“Mr. Flynn was set to become the national security adviser, and it was untenable that Russia — which the intelligence community had just assessed had sought to interfere in the U.S. presidential election — might have leverage over him,” Mary McCord, the Justice Department's top national security official at the time, wrote in a New York Times opinion piece in which she accused Barr of misrepresenting her viewpoints.

U.S. District Judge Emmet Sullivan has yet to rule on the Justice Department's dismissal request and has indicated that he is not inclined to do so swiftly. (AP)
