“How strange is it for you to sit here and compare the president to a mob boss?” host George Stephanopoulos asks Comey in a clip shared by ABC News. 

The preview also shows Stephanopoulos asking Comey if he believes President Trump obstructed justice and if he thinks the president should be impeached.

Comey does not speak at all in the promotional clip.

The interview is set to air on Sunday night. It will be Comey’s first television interview since he was fired by Trump last May. 

Comey is also scheduled to sit down for an interview with CNN’s Jake Tapper on April 19 and to participate in a CNN town hall event on April 25. 

The media blitz coincides with the release of Comey's book, “A Higher Loyalty: Truth Lies & Leadership,” on April 17.
