Mark (aka Markus) Garrison, who was booted off The Apprentice last night, isn't done with the Donald. Rankled by what he calls "lazy, hugely dishonest editing" that painted him as "Markus, the motormouth doofus," the 41-year-old inventor tells, "I'm issuing a public challenge to Trump to have a debate anywhere, anytime and on any subject, for five minutes, 10 minutes, on Dr. Phil, Oprah, whatever. I'll bury the guy." Or at least talk him into submission.
