McCabe said officials looked at the following events:

Trump asked former FBI Director James Comey to drop the investigation into former national security adviser Michael Flynn.

Trump asked Deputy Attorney General Rod Rosenstein to “include Russia” in a memo the President requested outlining reasons to fire Comey (which Rosenstein did not do).

Trump fired Comey.

Trump made public comments linking his firing of Comey to the Russia investigation on NBC.

Trump met in the Oval Office with Russian officials where Trump reportedly said that firing Comey relieved “great pressure.”
