 Anytime the president called Mike Pence, his vice president, even if he asked him to do something that the public might have thought was untoward, he has the right to call his vice president. That's a conversation that's within the scope of his duties. Calling up the Justice Department and discussing what kinds of things might be done about the election. Hey, it's his Justice Department. If he wants to call them up and talk to them, it's part of his official duties. Also, they said the motives of the president don't matter.
