Sen. Jeff Flake visited Sen. John McCain at his cabin in Arizona on Saturday and said McCain is "gaining strength."
McCain was diagnosed with an aggressive form of brain cancer over the summer and has been recovering in his home state.
Flake posted on Twitter about his visit with McCain and said: "Had a nice visit with @SenJohnMcCain today. He's working hard and gaining strength."
Flake's visit came the same day CNN aired an episode of "The Van Jones Show" in which McCain's daughter, Meghan McCain, said her dad is "doing really good, all things considered."
