WASHINGTON — Arizona Republican Sen. John McCain plans to return to Washington soon, sources close to the senator tell CNN.

McCain was diagnosed with a brain tumor in July. In December, it was announced that he would return home to Arizona to recover from cancer treatment instead of returning to the Senate to vote on a finalized version of the GOP-backed tax plan.

McCain is feeling better following his recovery in Arizona, the sources said.

A specific date for his return has not yet been determined.
