U.S. Federal Reserve Chair Jerome Powell has requested a renewed investigation into the ballooning costs of the Federal Reserves building renovations, now estimated at $2.5 billion, according to a report from Politico.

Trump's push to oust Jerome Powell over interest rates and Fed renovation costs highlights growing tensions around economic inequality and political control.

Kevin Hassett, an economic adviser to President Donald Trump, said that the Federal Reserve chairman had "a lot to answer for" about a pricey office renovation.
