James Comey testified Thursday that President Trump told him "I need loyalty" and directed him to back off the investigation of Michael Flynn. Trump, via his lawyer, denied both of those claims.
The reactions to those comments exposed a notable split between Trump's inner circle and other high-profile Republicans, many of whom seemed to take Comey's version of events at face value.
Why it matters: As the Russia "cloud" casts a wider shadow across the Trump administration, the president will need his party to remain firmly behind him to avoid disastrous results. While the statements thus far don't indicate that Trump has lost his party, they do indicate that he doesn't have the implicit trust of many top Republicans.
