Pass emergency bipartisan legislation to require disclosure and separation of Trump's and his family business interests from his functions as president. This should apply to all presidential candidates/ presidents elect going forward.
Why is this important?
There are too many potential issues of conflict of interest, bribery, manipulation of foreign policy and undermining of military interests to allow non-disclosure of business interests to Congress. In addition, family members of Trump (or any president's family) should be exempt from consideration for access to classified materials, just as they are prohibited from holding formal positions in the administration.
