WATCH: Mark Levin Calls Obama a 'Serial Liar,' and Accuses Him of 'Hollowing Out the Military'

At the final presidential debate Monday night, President Obama criticized Mitt Romney for not understanding the needs of the current-day U.S. military.

In one of the most talked-about statements from the debate, Obama said, "You mentioned the Navy, for example, and that we have fewer ships than we did in 1916. Well, Governor, we also have fewer horses and bayonets, because the nature of our military’s changed.”

In case you were wondering, Fox and Friends pointed out this morning that the Army actually still has 419,155 bayonets and 176 horses, while the Navy has 195,334 bayonets in use. Brian Kilmeade talked to national radio host Mark Levin about the president's remarks.

Levin said the remark was ignorant, and accused Obama of "hollowing out the military more than Jimmy Carter did."

"He's slashing maintenance, he's slashing R&D, he's slashing replacement units, and it's not just the Navy, it's the Air Force and the Army," said Levin.
