Former Alaska Gov. Sarah Palin, the running mate of John McCain in the 2008 presidential election, reacted on "Tucker Carlson Tonight" to the news of the Arizona senator's brain cancer diagnosis

"He is a fighter," she said, adding she believes Sen. McCain will soon remind everyone to "use hardship as fuel to endure" in this trying time.

McCain, chairman of the Senate's Armed Services Committee, was found to have an aggressive form of cancer. It was discovered by doctors after he had surgery on Friday to remove a blood clot from above his left eye.

Palin said personal loyalty is rare today in politics, but Sen. McCain has "embodied loyalty" toward her family. 

"If I were going to war, I wouldn't just want him on my side, I'd want him leading the charge," said Palin.

Palin said she spoke to McCain "relatively recently" and they always "have a good laugh" about their shared experiences on the campaign trail and in the public eye. 

She said she hopes everyone will stop "cruel" politically-driven comments in this environment and "understand what really matters."

Palin applauded the "beautiful" statement shared by McCain's daughter, Meghan.
