Federal Reserve Bank of Atlanta President Dennis Lockhart said in an interview on Bloomberg television Friday that the interest rate hike by the Fed in September is still possible. But he added that there is a risk now.

"We are sort of anxious to get going, but given the events of the last several weeks, a risk factor has arisen. It has to be considered an open question whether we move now or wait a little while," he said.

Lockhart is a voting member of the Federal Open Market Committee (FOMC) this year.
