Former FBI Director James Comey won’t testify that President Trump obstructed justice in the FBI’s investigation into alleged ties between the Trump campaign and Russia, according to a new report.

A source familiar with Comey’s thinking on the matter told ABC News that Comey will not say Trump interfered with the FBI’s investigation, but will dispute Trump’s assertion that the former FBI director told me three times that he is not under investigation.

“He is not going to Congress to make accusations about the President’s intent, instead he’s there to share his concerns,” the source told ABC News.

Comey is set to testify Thursday before the Senate Intelligence Committee after being fired by Trump in May.

In a signed letter from Trump to Comey, Trump said it was time for a “new beginning” at the FBI.

“While I greatly appreciate you informing me, on three separate occasions, that I am not under investigation, I nevertheless concur with the judgment of the Department of Justice that you are not able to lead the Bureau,” Trump wrote.

Trump cited investigations into Russia’s interference in the 2016 presidential election in explaining his decision to fire Comey in May.

“Regardless of recommendation, I was going to fire Comey,” Trump said during an interview on "NBC Nightly News in May, insisting "there was no good time to do it."

“And in fact, when I decided to just do it, I said to myself, ‘You know, this Russia thing with Trump and Russia is a made up story,’” Trump continued.

“It’s an excuse by the Democrats for having lost an election that they should have won ... This was an excuse for having lost an election.”
