Arizona Gov. Doug Ducey is optimistic about the health of Sen. John McCain, R-Ariz., after talking with his wife Cindy McCain several days ago.

"This weekend, I talked with Cindy, I got a really good report from her," Ducey, a Republican, said during a radio interview with KTAR-FM on Tuesday. "She said the senator is up and at 'em, and is bossing everyone around, so very much back in his element. So, I'm rooting for him."

The senator, who is 81 years old and was diagnosed in July with a primary glioblastoma, was hospitalized last week. After he missed votes on Monday and Tuesday, it was revealed he was "receiving treatment at Walter Reed Medical Center for normal side effects of his ongoing cancer therapy," according to a statement from his office.

Cindy McCain revealed on Monday she and her husband had traveled back to Arizona for Christmas. The family said in a statement that the senator would be undergoing physical therapy and rehabilitation and that they anticipate he will return to Washington in January.

“It seems like he’s getting healthy again,” Ducey added. “I know he’s going to be headed back to Washington at the turn of the calendar year, so I’m excited. I think it’s really good news.”
