Why he has taken the fifth:

I once asked, “if you’re innocent, why are you taking the Fifth Amendment?” Now I know the answer to that question. When your family, your company, and all the people in your orbit have become the targets of an unfounded, politically motivated Witch Hunt supported by lawyers, prosecutors, and the Fake News Media, you have no choice. If there was a question in my mind, the raid of my home, Mar-a-Lago on Monday by the FBI, just two days prior to this deposition wiped out any uncertainty. I have absolutely no choice because the current Administration and many prosecutors in the Country have lost all moral and ethical bounds of decency.

Accordingly and under the advice of my counsel and for all of the above reasons, I declined to answer the questions under the rights and privileges afforded to every citizen under the United States Constitution.
