A second potential whistleblower with more direct knowledge of President Donald Trump's apparent criminal activity toward Ukraine has contacted the intelligence community's inspector general and is considering coming forward and testifying before Congress.

This individual, who like the first whistleblower is also an intelligence official, has not yet filed an official whistleblower complaint, The New York Times reports.

The second whistleblower was one of the intel professionals the inspector general interviewed to corroborate the facts presented by the first whistleblower.

The intelligence community inspector general, Michael Atkinson, has already notified Congress there is a potential second whistleblower.
