From a report at the link below:
In his first foreign trip in the second term of President Barack Obama's presidency, Vice President Joe Biden is gaffing his way across Europe.
After attending a national security council meeting in the UK, Biden said that he was "delighted to do it, I spent half my life on OUR national security council,"
The truth is Biden has only been on the U.S. National Security Council for four years--not the 35 years he suggested.
Biden also got Portugal mixed up with Poland. The British press called it the "latest embarrassing gaffe for the vice president."
