Jan. 26 (Bloomberg) -- JPMorgan Chase & Co. Chief Executive Officer Jamie Dimon told CNBC he might support Warren Buffett’s proposal for tax increases, and that the U.S. should have a “conversation” about tax rates.

Dimon, interviewed by CNBC at the World Economic Forum in Davos, Switzerland, also said he’s “still barely a Democrat” and hasn’t decided how to cast his vote for president. Ben S. Bernanke has been an “outstanding” chairman of the Federal Reserve, Dimon said.
