They also sent a letter to the FBI asking for any records of any communications between Comey and Trump before May 24.
That should be a barnburner, if Comey agrees to testify. He pretty much has two options. If he says that he told me to drop the case, then he, Comey, has to explain why he covered it up and didn’t report it, a potential felony. If he says that isn’t what he said, then he’s going to get raked over the coals by Democrats insisting he’s colluding with Trump to cover himself anyway.
The reason why whoever leaked this memo, if it exists, did Jim Comey no favors….
