'A dangerous man' -Warren opposes Powell's renomination to Fed

Warren of Massachusetts, a long-time critic of the Fed's oversight of Wall Street and member of the committee that reviews appointments to the Federal Reserve board, said having Powell appointed to a second term as the central bank's chief is "not a risk worth taking."

The White House has not yet announced a decision on whether to reappoint Powell, whose term as chair ends in February, or choose an alternative.
