"Unmasking" is a process by which an authorized official with a "need to know' requests access to a private citizen's name that is the subject of a federal wiretap", wrote Johnson, R-6 OH, in a statement Thursday.
"If I were a Senator or Congressman, the first person I would call to testify about the biggest political crime and scandal in the history of the United States of America, by FAR, is former President Obama", Trump wrote on Twitter.
Late past year, Flynn's lawyers alleged FBI agents doctored the 302, but federal prosecutors denied that the notes had been changed in any significant way.
"Unmasking" refers to revealing the identity of someone on a monitored communication from US intelligence agencies. "The intelligence report would refer to the person only as "U.S. Person 1" or U.S. Person 2". Flynn pleaded guilty to lying to the Federal Bureau of Investigation about conversations with the Russian ambassador to the United States during the presidential transition period.
In addition to Mr. Bell, a total of eight other North Atlantic Treaty Organisation officials sought the unmasking of an American or Americans listed in NSA intelligence reports on December 15 and 16.
Former Vice President Joe Biden said Thursday that he would not pardon President Donald Trump if elected and insisted any prosecutorial decisions would be left to a more independent Justice Department.
Unmasking itself is not illegal. In 2018, the NSA, which does most unmasking, revealed the identities of 16,721 US persons, according to the Office of the Director of National Intelligence.
Mr. Bell is now chief executive officer of National Security Counsel, a consulting firm based in Florida.
Names of Americans picked up in Us surveillance of foreign individuals are routinely hidden in intelligence reports that describe.
Biden campaign reacts to Flynn unmasking revelations by attacking journalist & denouncing Republicans
While unmasking is a common practice, leaking an unmasked name to the media or the public is illegal. Here's everything you need to know about the latest Flynn developments.
The list shows that Dempsey made a request for Flynn's identity on January 7. "When a name is unmasked, the underlying intelligence to include the name remains classified so leaking it would be a crime".
On Thursday morning, Trump claimed via Twitter that his predecessor "knew EVERYTHING" about the "biggest political crime and scandal in the history of the U.S.", a baseless conspiracy theory that Obama was somehow involved in Michael Flynn's criminal case (Trump has yet to actually explain in detail what the "crime" was or provide any evidence of its existence, let alone Obama's supposed involvement in it).
It listed officials in Obama's administration - including Biden - who may have learned about actions by Flynn in late 2016 and early 2017 through so-called unmasking requests.
It showed that Biden, then the vice president, was among dozens of senior Obama administration officials who may have learned of Flynn's phone conversations with the Russian ambassador, who was under routine surveillance by USA intelligence agencies, after Trump's election but before he took office.
Then on Wednesday, Republican senators released a memo that had been marked "Secret" until Grenell declassified it.
For example, in a Hulu documentary about Hillary Clinton's 2016 campaign against Trump, the Virginia senator Tim Kaine is seen to say the then president thinks Trump is a fascist.
Democrat Joe Biden (R) is likely to face off against Republican Donald Trump in the November 2020 presidential election.
Biden has denied wrongdoing in the unmasking saga.
Graham also suggested it's inappropriate for the sitting president to accuse his predecessor during the CCP virus pandemic, or vice versa.
"It's no surprise that the president is erratically lashing out at President Obama, desperate to distract from his own failures as commander in chief that have cost thousands of Americans their lives during this crisis", TJ Ducklo, a Biden campaign spokesman, told the Associated Press news agency.
