Rachel Maddow mocks Republican parade of misinformation at Las Vegas debate

MSNBC host Rachel Maddow went from amused to alarmed on Wednesday as she highlighted several false claims by Republican presidential candidates during their debate a night earlier.

"It was that kind of night," Maddow repeated, with growing frustration.

For example, Maddow noted, Carly Fiorina insisted she would bring back what she called the "warrior class" -- former generals she said retired because they told President Barack Obama "things that he didn’t want to hear."

After explaining that David Petraeus and Stanley McChrystal both resigned because each became embroiled in a controversy, Maddow played a clip of ex-Army vice chief of staff Jack Keane confirming to Fox News that Obama couldn't have forced him to retire, because he served in George W. Bush's administration and retired in 2003.

"This is freaking amazing," Maddow said as she introduced Keane's rebuttal.

The host also pointed out that, despite what New Jersey Gov. Chris Christie (R) claimed, Obama did not "invite Russia into Syria" during his administration -- Russia has actually had an outpost there for more than 40 years.

"Gosh darn you, Barack Obama, for traveling back in time and inviting Russia into Syria when you were 10 years old in 1971," Maddow quipped. "That was so reckless."

But she was less enthused after playing footage of Republican front-runner Donald Trump stumble through an answer regarding the country's "nuclear triad." For the country's national security policy to advance, she said, both major political parties need to be skilled in the issue.

"Can the Republican Party hold up its end of the debate?" she asked. "What would the Republican Party become on national security after the disaster of Bush and [Dick] Cheney? Huge question. Huge, important question. Please, God, let this not be their final answer."
