Warren Buffett told CNBC that new Federal Reserve Chairman Kevin Warsh was a good choice for the job. Warsh held rates steady at his first meeting in June and outlined changes to the central bank's approach, later pledging a regime change in Fed policy and a commitment to tackling inflation during Congressional testimony. Buffett said he believes Warsh will do his best to achieve 2% inflation and maximum employment, though he acknowledged no one can be perfect at the task. Warsh took the helm in May after being nominated by President Donald Trump and confirmed by Congress, and is set to testify before the Senate Banking Committee on Wednesday.
