Comey Almost Definitely Leaked Twice, and Therefore Lied to Congress
Isaac Simpson

Two other possibilities that don’t involve Comey lying about a largely inconsequential detail while under oath: 1) The May 11th leak worked at the FBI and had access to the memos; 2) The May 11th leak has a good memory or had recently talked to Comey about his conversations with Trump and leaked to the NYT independently. 
Occam’s Razor and all.

Of course, if Comey’s lying about this little detail, he may be lying about other things. Trump should release his secret tapes and settle all of this.
