Sen. John McCain, R-Ariz., spent the weekend outdoors, relaxing.
On Sunday afternoon, McCain, 80, who underwent blood clot surgery this month and was diagnosed with glioblastoma, tweeted a photo of himself with a friend.
"Enjoying Zebra Falls in beautiful Oak Creek, #Arizona today with my friend Joe Harper," he wrote.
Dressed in jeans, an unbuttoned long-sleeve khaki shirt over a T-shirt and a navy cap with a neck flap for protection against the sun, McCain was seated on a rock, smiling, with his feet in the water.
On Saturday, his daughter Meghan McCain shared a photo with her father, both on a bench looking out at the view.
