Former Vice President Joe Biden says a White House official's comments about Sen. John McCain showed when "decency would hit rock bottom with this administration."

Biden is responding to the dismissal of McCain's opposition to President Donald Trump's CIA nominee. The aide, Kelly Sadler, said "it doesn't matter" because "he's dying anyway." That's according to two people, who were in the room at the time and who spoke to The Associated Press.

Biden, a Democrat, says McCain is a genuine hero and "he deserves better - so much better."

Biden says that given the White House's trail of disrespect toward McCain and others, the aide is not an exception to the rule, but the "epitome of it."

Biden also says children learn from example and the lingering question is whose example it will be. He says "I am certain it will be John's."

On "The View" Friday, McCain's daughter, Meghan, also responded to the Sadler's comments.

"I don't understand what kind of environment you're working in when that would be acceptable and then you could come to work the next day and still have a job."
