In the summer of 2015, shortly after launching his presidential campaign, Trump mocked McCain's war service, saying of the 2008 Republican presidential nominee: "He's not a war hero".
On Thursday night, a report broke revealed that Trump staffer Kelly Sadler took a shot at McCain dealing with brain cancer after the senator refused to endorse the president's pick to lead the Central Intelligence Agency.
She told reporters she's "not going to validate a leak out of an internal staff meeting one way or the other".
Sanders said the leak was selfish and distracted from the president's agenda and "everything we're trying to accomplish for the American people", according to a person familiar with the meeting who spoke on condition of anonymity to describe the private meeting.
"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", Biden said in his statement.
She reportedly called Meghan McCain, the senator's daughter, to apologize on Thursday evening. Certainly there is not a tone set here.
Mulvaney told Fox News that in doing so, Sadler handled the situation "appropriately".
Sadler is still employed at the White House, Sanders said Friday. "It happened yesterday (Thursday)", Biden said in a striking statement.
Central Intelligence Agency director nominee Haspel weighed in with a statement Thursday night, saying "I have the utmost respect for Sen".
The White House issued a statement Thursday: "We respect Sen".
A FOX Business spokesperson confirmed to ABC News that McInerney will no longer be invited to appear as a guest on either FOX Business Network or FOX News Channel.
As for the president, he and McCain have had a troubled relationship.
Payne also issued a lengthier apology, saying he regrets not interjecting when retired general Tom McInerney initially made those remarks.
The 81-year-old senator was diagnosed in July with glioblastoma, an aggressive brain cancer.
McCain has recounted stories of lying to his interrogators under torture, including giving them the names of the Green Bay Packers' offensive line instead of the names of his own squadron. "I really feel like I understand the meaning of life, and it is not how you die, it's how you live", she said.
