He really can’t testify that he did. Because if he did, he’d have to explain why he didn’t report it. So he’s going to try and criticize him as much as he can without boxing himself into a corner.
Comey will stop short of saying Trump obstructed justice in Flynn probe, source saysVia ABC:
There will be much in former FBI Director James Comey’s upcoming congressional testimony that will make the White House uncomfortable, but
he will stop short of saying the president interfered with the agency’s probe into former national security adviser Michael Flynn, a source familiar with Comey’s thinking told ABC News.
Although Comey has told associates
he will not accuse the President of obstructing justice, he will dispute the president’s contention that Comey told him three times he is not under investigation.
The president allegedly said he hoped Comey would drop the Flynn investigation, a request that concerned Comey enough that he documented the conversation in a memo shortly after speaking with the president. In the memo, according to sources close to Comey who reviewed it, Trump said: “I hope you can see your way clear to letting this go, to letting Flynn go,” during a February meeting.
The request made Comey uncomfortable, but the source tells ABC News that Comey has told associates he will not accuse the President of obstructing justice.
