You should talk, Lyin’ Brian!

Brian Williams, who was bounced from his NBC anchor job for fabricating stories, is furious about the spread of “fake news.”

The talking head, who was forced to take a six-month vacation last year before being permanently relieved of his “Nightly News” duties on NBC, railed about the epidemic of “fake news” on his late-night MSNBC cable show this week.

“Fake news played a role in this election and continues to find a wide audience,” he whined Tuesday night on “The 11th Hour with Brian Williams.”

Specifically, Williams singled out President-elect Donald Trump’s pick for national security adviser, retired Army Lt. Gen. Michael T. Flynn, and the general’s son, Michael G. Flynn, for irresponsibly spreading falsehoods.

“Flynn’s son was fired by the Trump transition team today for passing on fake news stories via Twitter,” Williams said. “But his dad, the retired Army three-star general, has passed on some gems himself.

“Here are a few: [Hillary] Clinton is involved with child sex-trafficking and has secretly waged war on the Catholic Church, as well as charges that the president is a jihadi who laundered money for Muslim terrorists.”

But Williams is hardly a model of honest journalism. He was punished in February 2015 for falsely claiming during a broadcast a month earlier to have been aboard a helicopter that was struck by enemy fire during a 2003 flight in Iraq.

Questions were also raised about Williams’ coverage in the aftermath of Hurricane Katrina in New Orleans in 2005.

Williams claimed he could see bodies amid flooding from his hotel room in the French Quarter.
