White House says aide's remark about McCain being handled 'internally'

The White House on Monday again refused to apologize for staffer Kelly Sadler's derisive comment about Sen. John McCainJohn Sidney McCainTrump blasts McCain, bemoans not getting 'thank you' for funeral Trump's approval rating stable at 45 percent GOP senator: Trump's criticism of McCain 'deplorable' MORE, saying the matter is "being addressed internally."

White House spokesman Raj Shah confirmed that Sadler called McCain's daughter, Meghan, to apologize for her remarks but indicated a public apology will not be forthcoming. 
“I understand the focus on this issue, but it is going to be dealt with and has been dealt with internally," Shah told reporters. 
The comments created a multiday firestorm, which the White House is struggling to dig out of in part because it has refused to offer a public apology — as members of McCain's family and lawmakers in both parties have requested. 
Shah condemned the leak of the remark, but declined to discuss his thoughts on the comments themselves. 
"If you aren’t able, in internal meetings, to speak your mind or convey thoughts or say anything that you feel without feeling like your colleagues will betray you, that creates a very difficult work environment," he said. 
The spokesman said the matter "is not about my opinion or anybody else’s opinion."
Shah was leading the meeting when Sadler made the remark.
