[Donald Trump] has moved to admit that there is a conflict of interest now and he needs to do something.

[Donald Trump] faces a lot of problems.Why go there?

What about the golf courses?What about the huge foreign bank loans?What about the condos and the apartments that they sell, the promoting and the trademarks?[ Jason] Chaffetz should be investigating the president-elect's impeding violation of the constitution, not this poor government official who is just trying to do his job. And Mr. Chaffetz has endorsed that unconstitutional plan.

With the new Russia allegations coming to the fore once again, the conclusion of the intelligence agencies, we've got to have those [Donald Trump's] taxes to evaluate whether these conflicts go to the heart of our most pressing national security interests.

There's a Russia angle to all this, because remember, we don't have Donald Trump's tax returns. He did a very - relative summary, 104 page campaign financial disclosure. One year of tax returns, reportedly - we've seen the pictures, 12,000 pages. And tax returns are replete with his foreign interests, including, perhaps, his Russian interests. That may be the reason he doesn't want to turn over his taxes.

People are studying whether there's a cause of action that competitors, for example, would have if they're harmed by these foreign government payments.

There's going to be a lot of remedies. [Donald Trump] is also subject to other conflicts laws.The bribery laws are intended to prevent conflicts, for example. He's subject to criminal law. He's subject to civil law. He's going to be subject to litigation. He's already in a lot of cases. This is going to come up in existing litigation and there's going to be new litigation.
