Russia Today reports former Director of National Intelligence "knowingly lied to the US Select Committee on Intelligence" when Clapper responded to Sen. Wyden that the NSA did "not wittingly" engage in mass surveillance of Americans. When later confronted about the testimony, Clapper summed up his conduct as responding in the "least untruthful manner."

It has been 5 years, since Clappers testimony, and since it Edward Snowden revealed to everyone how the surveillance state seems to have magically amended the fourth amendment to permit them to spy on us like cattle through our TVs, phones, webcams and possibly much much more.

Various lawmakers called for Clapper to face prosecution, but that has not happened and may be too late now due to the statute of limitations. Clapper may no longer be able to be charged with perjury--though the RT article does not mention if the SOL might be tolled until reasonable notice of the perjury may have occurred. But the total nature of US law is unclear and mostly out of the hands of the people as demonstrated by the possibly extra judicial shredding of the fourth amendment. The RT article reports one legislator's view:

"He admitted to lying to Congress and was unremorseful and flippant about it,” Rep. Thomas Massie (R-KY) told the Washington Examiner. “The integrity of our federal government is at stake because his behavior sets the standard for the entire intelligence community.” Massie was referring to Clapper, not the baseball player. Just to be clear.

Past testimonies to Congress didn't get the Clapper treatment such as J Steven Griles in regards to crimes of Jack Abramoff and Miguel Tejada in regards to professional baseball. Other theories of why Clapper didn't give the most accurate testimony other than the least truthful manner, as Clapper babbled to Sen. Feinstein--who herself was spied on by the intelligence apparatus regarding investigations into torture-- asserting he just didn't think about the metadata collection program.
