Sen. Ben Cardin, D-Md., said Friday that President Trump needs to apologize for comments made by White House aide Kelly Sadler, who said it doesn’t matter what Sen. John McCain, R-Ariz., thinks because he’s “dying anyway.”

“I would like to hear something from the president of the United States,” Cardin said on CNN Friday. “The president should be saying that this was unacceptable under my watch, I will not tolerate such comments. But we haven’t heard a word from the president.”
