WATCH: Katrina Pierson Blames Obama for Capt. Khan’s 2004 Death - 5 Years Before Obama Took Office

Donald Trump national spokesperson Katrina Pierson failed epically during her CNN interview Tuesday night, when she mistakenly thrust blame on Obama while defending the Donald. Pierson often goes to great lengths to defend her boss, but this was clearly inexcusable. 

Regarding Trump's remarks about Khizr and Ghazala Khan Saturday, CNN's Wolf Blitzer asked Pierson, "Has Mr. Trump called the Khan family and apologized?"

But Pierson, echoing Donald's son Eric's remarks, believes Trump has apologized "by honoring the soldier," she declared. 

When Blitzer tried pressing Pierson for more information, or rather empathy, that's when things took a turn for the worst. 

“What exactly is Mr. Trump supposed to be apologizing for, just so I’m clear?" she asked the CNN host, dumbfounded. 

“Wasn’t he disrespectful ... to that Gold Star family?” Blitzer asked her.

“Disrespectful by defending himself?" the spokesperson blundered. "The only thing he said, Wolf, is basically, ‘This man knows nothing about me. Why is he criticizing me?’ How is that an attack?"

"It was under Barack Obama and Hillary Clinton that changed the rules of engagement that probably cost his life. So I don’t understand why it’s so hard to understand why Donald Trump was confused," Pierson shot back.

Actually it couldn't have been Obama's fault, as Pierson claimed: Capt. Khan was killed in Iraq five years before President Obama took office.
