Atlanta Fed President Dennis Lockhart said on Tuesday that the Fed could raise its interest rate in June.
"I wouldn't take it off the table," he said.
Lockhart noted that the Fed could hike its interest rate two or three times this year.
Atlanta Fed president also said that the referendum on Britain's membership in the European Union would not be a reason for the delay in raising interest rate.
Lockhart is not a voting member of the Federal Open Market Committee (FOMC) this year.
