White House spokeswoman Sarah Huckabee Sanders said later that Ms Sadler still worked at the White House, and refused to confirm or deny what Ms Sadler had said.
Congressman Walter Jones is speaking out about reports that a White House communications staffer made an insensitive remark about Senator John McCain, who is battling brain cancer.
Sadler was discussing McCain's opposition to Trump's pick for Central Intelligence Agency director, Gina Haspel, at a communications staff meeting on Thursday when she said that, "it doesn't matter" because "he's dying anyway", two people in the room confirmed to The Associated Press.
"Given this White House's trail of disrespect toward John and others, this staffer is not the exception to the rule; she is the epitome of it".
"I regret I did not catch this remark, as it should have been challenged", Payne said.
Sadler is a special assistant to the president.
The official said Sadler meant it as a joke, "but it fell flat".
"John McCain fought for us in Vietnam, was a prisoner of war in Vietnam, came home and dedicated his life to public service", Ryan said of the six-term Arizona Republican senator.
"My father's legacy is going to be talked about for hundreds and hundreds of years", she said."That's why they call him Songbird John", McInerney said on Thursday on Fox Business Network.
Her father is "all about character and bipartisanship and something greater than yourself", Meghan McCain said, before adding a stinging message to the critics: "Nobody's going to remember you". On ABC's The View this morning, Meghan McCain said, "Kelly, here's a little newsflash, and this may be a bit intense for 11 o'clock in the morning on a Friday, but we're all dying".
Sen. McCain, a Navy pilot who was beaten in captivity during the Vietnam War, has urged his fellow senators to reject Haspel.
Haspel faced grilling Wednesday by the Senate Intelligence Committee about her role overseeing some CIA operations after the September 11 attacks. Her refusal to acknowledge torture's immorality is disqualifying.
As for the president, he and McCain have had a troubled relationship.
Mr McCain was the Republican Party's presidential candidate in 2008.
Last July, McCain became the deciding vote against the GOP health care repeal with a dramatic thumbs-down. "That is something we try to do in both word and action".
"We plan for a full day of meetings on the 12th with some time reserved to carry over if necessary", Sanders said.
