Possible dissents by Christopher Waller and Michelle Bowman would mark the first time in three decades that more than one Fed governor dissented at a policy meeting.

The Federal Reserve left its benchmark interest rate unchanged Wednesday, but a rate cut is possible in September. President Trump has been urging the central bank to lower borrowing costs.

Trump argues that because the U.S. economy is doing well, rates should be lowered. But unlike a blue-chip company that usually pays lower rates than a troubled start-up, the Fed adjusts rates to either slow or speed growth, and would be more likely to keep them high if the economy is strong to prevent an inflationary outbreak.
