While campaigning in Scranton, Pennsylvania today -- according to the Politico -- Vice President Joe Biden said in talking about our campaign contributions:

"I challenge the Chamber of Commerce to tell us how much of the money they’re investing is from foreign sources. I challenge them. If I’m wrong, I will stand corrected."

We accept the Vice President's challenge here and now, and are happy to provide our answer: 

Zero. As in, "Not a single cent." 

We hope this clears it up, and hope the Vice President keeps his word and stands corrected.
