https://www.congress.gov/bill/115th-congress/senate-bill/720From the Summary:
"The bill prohibits U.S. persons engaged in interstate or foreign commerce from:
requesting the imposition of any boycott by a foreign country against a country which is friendly to the United States; or
supporting any boycott fostered or imposed by an international organization, or requesting imposition of any such boycott, against Israel."
Jesus that is really vague and overbroad. Should not survive the courts if its passed.
