The Fed’s decision on interest rates affects many types of consumer borrowing costs, from credit cards and mortgages to auto loans.

President Donald Trump’s attempt to shame Federal Reserve Board of Governors chair Jerome Powell over the cost of a long-running renovation to the central bank’s Washington headquarters went horribly wrong on Thursday when Powell had a ready response for the president’s accusations during a tour of the construction site.

Trump has used the renovation project as both a literal and symbolic example of what he has often described as government waste. Speaking to reporters last week, Trump called the construction effort “a disgrace,” and accused Fed officials of overspending at a time when inflation remains high and interest rates are biting into household budgets.
