Traders were weighing the odds of a resolution to the trade war with China after President Trump on Friday indicated he was cool to any agreement. Trump said no agreement on tariff reductions had been reached and, in any case, there’s no chance tariffs would be eliminated entirely.

Democrats planned to open the public phase of the impeach inquiry Wednesday with testimony from two diplomats at the center of the controversy over whether Trump tried to pressure Ukraine into investigating his political rivals in exchange for military aid. The president started the morning by railing against the investigation, saying transcripts released last week were “doctored.”

Trump praised Dimon for saying in the interview that the tariffs brought China to the table.
