“I’m staying,” Cohn said during an event sponsored by Axios.

The National Economic Council chairman said he is eager to participate in upcoming efforts to overhaul the welfare system and pass an infrastructure bill.

“It’s a once-in-a-lifetime opportunity,” he said.

Cohn is seeking to push back on widespread speculation he would leave the administration after the completion of the GOP tax push.

The former Goldman Sachs president had been seen as one of the president’s closest advisers and was even considered as the next Federal Reserve chairman.

But his relationship with the president suffered after he criticized Trump’s reaction to the racially charged violence at a white supremacist rally over the summer in Charlottesville, Va.

While their relationship eventually improved, speculation still swirled about Cohn’s future in the White House after tax reform wrapped up.

Cohn's departure would be a blow to a White House that is expecting to lose a number of top advisers early next year.

Deputy national security adviser Dina Powell, an ally of Cohn, has already announce she plans to leave her role in January.

Omarosa Manigault Newman, the top communications aide for the White House Office of Public Liaison, is also leaving.
