White House Legal Team Considers Ways Trump Could Testify Before Mueller

Mr. Trump is a freewheeling conversationalist, an instinct that proved advantageous on the campaign trail but could be unsuited to a legal setting.

“As a lawyer, what I would want to get a sense of is how careful my client is going to be when responding to questions,” Mr. Gonzales said. “If I’m totally confident that this person can be careful in saying no more than needs to be said, I might let my client go ahead and testify.”
