Al Franken knows a lie when he hears it. He wrote a book about “Lies and the Lying Liars Who Tell Them.”

The U.S. senator from Minnesota stood on the Senate floor and offered a point-by-point rebuttal of an apparent lie that Donald J. Trump likely told about a recommendation he got to fire FBI Director James Comey.

Then again, perhaps the lie came from the mouth of Attorney General Jeff Sessions, who announced this year he would “recuse” himself from any dealings at any level with the probe into whether Russian government officials sought to influence the 2016 presidential election in the president’s favor.

You see, the president said he got a recommendation to fire Comey from — drum roll! — AG Sessions, the fellow who said he would recuse himself from this matter.

Oh yeah! Then there’s that matter of Comey leading the FBI probe into allegations that the Trump campaign colluded with Russian hackers to sway the election.

Sen. Franken’s statement zeroes in quite cleanly on Sessions’ recusal and he casts doubt (a) on whether the president really got a recommendation from Sessions to fire Comey or (b) on whether Sessions has actually recused himself as he pledged to do.

Man, this Comey firing matter is beginning to get stinkier by the day.
