Treasury Secretary Steve Mnuchin isn't giving up on tax reform, promising that the issue will be handled by the end of the year, and said that tax reform could be backdated to January 1.

The Trump administration has had trouble implementing its agenda so far, but Mnuchin told the Delivering Alpha conference in New York Tuesday that tax reform remains an achievable goal for the administration.

Backdating "is still something we are considering and it would be a big boon for the economy," Mnuchin said. "We're going to get this done by the end of the year."
