Meghan McCain appeared on CNN to talk about her father's progress after he was diagnosed with glioblastoma, an aggressive form of brain cancer, last July.

She told Van Jones that her dad is 'doing really good, all things considered' according to The Hill.

McCain said 'He had sort of a bad bout at Christmas time. He was hospitalized at Walter Reed. He had ramifications from his chemotherapy. He had pneumonia. But he's made this, like, really incredible comeback.'

'I was with him at Christmas time and he was doing a lot of physical therapy and god bless his physical therapist who helps him because they are endlessly patient. He's doing good, it's really scary.'

She also said 'I feel guilty all the time for being here and doing my job. I have bonded with people I never thought I would have over this.'

In December John's office announced he had been hospitalized for 'normal side effects of his ongoing cancer therapy'.
