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 president hasn’t named a successor to Jerome H. Powell, but his insistence on someone who will lower interest rates has already raised doubts about their credibility.
