Online bargaining pool Groupon isn't exactly telling Donald Trump, "You're fired!" but it isn't endorsing the potential presidential candidate, either. The site has answered an online petition that erroneously called it out for sponsoring The Apprentice, a show under heighted scrutiny in the wake of Trump's hubbub regarding President Barack Obama's birth certificate.

On its blog, Groupon explained, "Groupon has never been a sponsor of The Apprentice on TV or on the web. We invest heavily in online advertising through networks that place ads on a rolling basis, meaning that we know one will appear on NBC.com but not specifically which page. We know that some advertising appeared on the Apprentice home page a few weeks ago."

Groupon promises that its ads will not appear on the Apprentice page in the future for "the same reason we don't run deals on guns or abortion...this isn't a political statement, it's avoiding intentionally upsetting a segment of our customers."
