The Democratic National Committee (DNC) is blasting Donald Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE, calling his statement that President Obama founded the Islamic State in Iraq and Syria (ISIS) "outrageous, unhinged and patently false."

“Donald Trump should apologize. ... This is yet another out-of-control statement by a candidate who is unraveling before our very eyes," DNC spokesman Mark Paustenbach said in a statement on Thursday.

"Combating terrorist threats like ISIS is a deadly serious undertaking, one that must be met with the unwavering resolve and steady temperament of a commander-in-chief that doesn’t fly off the handle at the slightest provocation."

"Donald Trump has once again shown that he lacks that temperament, and that he is simply unfit to hold our nation’s highest office,” Paustenbach added.

Trump on Wednesday said that Obama "founded" ISIS and should "get an award from them."

On Thursday, Trump doubled down on his comments, telling a radio host Hugh Hewitt that he meant every word.

"Last night, you said that the president was the founder of ISIS,” said Hewitt. “I know what you meant. You meant that he created the vacuum. He lost the peace.”

“No, I meant that he’s the founder of ISIS,” replied Trump. “He was the most valuable player. I gave him the most valuable player award."

Former CIA Director Michael Hayden also condemned Trump's remark on Thursday, saying that the GOP nominee "insults his audience" with his message.

"Does he not think that his audience could not accept the slightly more complex, slightly more reasoned message that this president made serious mistakes that led to the creation of ISIS? Why does he put it this way?” Hayden asked on MSNBC's "Morning Joe."

“Choosing those words corrupts the dialogue, corrupts what should be a very serious dialogue."
