“There are no red lines except what’s necessary to protect the country,” Rep. Adam B. Schiff (D-Calif.) said in an interview Monday. Schiff, the chairman of the House Intelligence Committee, told me he plans to request information, perhaps by subpoena, from Deutsche Bank, a major Trump lender, and that “our work on Trump’s finances has already begun.”
