NBC's Matt Lauer talked with Joe Biden about a op-ed in the Wall Street Journal where Biden came to the defense of Barack Obama on the issue of national security.

Biden told Lauer, "I'm saying is I'm sick and tired of Republicans characterizing Democrats, generally, as well as Barack and Hillary as being weak on national security. The truth is, we've never been weaker in the last 100 years in terms of our position in the world than under this administration."

Biden continued, saying, "I've never seen a time in the seven Presidents I've been with when america's been less respected around the world and has had less leverage, and the idea that we sit there and let this President and my friend, John McCain, characterize us as weak is just preposterous."
