WASHINGTON, July 13 (Reuters) - U.S. President Donald Trump has the authority to fire Federal Reserve Chair Jerome Powell for cause if evidence supports that, White House economic adviser Kevin Hassett said on Sunday, adding that the Fed "has a lot to answer for" on renovation cost overruns at its Washington headquarters.

The Trump administration’s intensifying campaign against Federal Reserve Chair Jerome Powell hit a boiling point Thursday.

Mark Calabria is now the Trump administration’s chief statistician, replacing Karin Orvis. The White House Office of Management and Budget has a new official leading and coordinating the U.S. government’s federal statistical system.
