President Trump denied both asking James Comey for a loyalty pledge, and pressuring him to drop the investigation into ousted national security advisor Michael Flynn when those claims emerged in news reports, attributed to anonymous sources.
Now Comey has gone on the record with the claims, which he will state Thursday in his testimony before the Senate Intelligence Committee.
ABC News' Jonathan Karl reports that Trump is standing by his denials: "The President firmly denies ever asking for Comey's loyalty or asking him to let the Flynn investigation go, a knowledgeable source tells me."
