Acting Director of National Intelligence Richard Grenell responded to a congressional request Wednesday by submitting a declassified list of Obama administration officials who had requested names be “unmasked” from Nov. 8, 2016 to Jan. 31, 2017.

Among those “unmasked”: incoming National Security Advisor Lt. Gen. Michael Flynn (Ret.).

And among those doing the “unmasking”: then-Vice President Joe Biden, who is now the presumptive Democratic Party nominee for the presidency in 2020.

Flynn, who was then the incoming National Security Advisor, spoke several times to then-Russian Ambassador Sergey Kislyak. The calls were picked up by U.S. intelligence, and Flynn’s name was leaked — illegally — to the media.

David Ignatius, a columnist for the Washington Post, reported Flynn’s conversations with Kislyak on Jan. 12. But reporter Adam Entous may have had the information first.

One call in particular — on Dec. 29, 2016 — attracted particular attention, because Flynn discussed the Obama administration’s new sanctions imposed that day on Russia for election interference. Flynn told Kislyak that Russia should not “escalate” in response, according to the report of Special Counsel Robert Mueller.

Flynn was later prosecuted for lying to the FBI about his conversations with Kislyak, though it is not clear what he told them.

On Tuesday, following reports that Grenell had declassified the list, Sens. Chuck Grassley (R-IA) and Ron Johnson (R-WI) wrote to Grenell asking for the list. On Wednesday, CBS News’ Catherine Herridge obtained a copy of Grenell’s response.

Grenell noted that the list was of those “who may have received Lt. Gen. Flynn’s identity,” though they may not have specifically requested Flynn’s name, and it could not be confirmed whether they had actually seen Flynn’s name.

Herridge  tweeted images of the list — and former Vice President Joe Biden’s name was on it, having asked for Flynn’s name to be “unmasked” on Jan. 12, 2017 — the same day that Ignatius’s column ran in the Post.

The tweets and list follow:

The names are presented in chronological order of their requests. Several of the names on the list are redacted.

Those who requested “unmasking” on or after Dec. 29, 2016 include: Power, Clapper, Lew, McDonough, Dempsey, O’Sullivan, Biden, and an unnamed person.

McDonough is the only person who made an unmasking request between Dec. 29, 2017 and Jan. 5, 2017.

That was the date of a key Oval Office meeting at which President Barack Obama met with several senior officials and informed Deputy Attorney General Sally Yates of the Flynn-Kislyak conversations.

At that meeting, the president also discussed Comey’s plan to approach President-elect Donald Trump  to inform him about salacious (and unverified) information from the “Steele dossier” at Trump Tower the next day, Jan. 6.

On Tuesday, in an appearance on ABC’s Good Morning America, Biden, who had been at the Jan. 5 meeting, initially denied knowing about the plan to investigate Flynn, then admitted that he had known that “they had asked for an investigation.”
