Atlanta Fed President Dennis Lockhart reiterated on Friday that the interest rate hike by the Fed this year is still possible.
"I see a lift-off decision later this year at the October or December FOMC meetings as likely appropriate," he said.
But he added that "the data are giving off varied signals, and there is more ambiguity in the current moment than a few weeks ago".
Lockhart pointed out that consumer spending data will be important "over coming months".
