Wheeler is a former homicide detective for the DC Metropolitan Police Department, who, per his LinkedIn, has been a contributor to Fox News since 2002. Wheeler is mostly known for saying outrageous things on air. In 2007, in reference to a controversy over racial profiling and policing, Wheeler pulled his eyes back on air to demonstrate what "a Chinese male" looks like. And in the same year, on the Bill O'Reilly show, Wheeler said that a "national underground network" of armed lesbians were raping girls. In addition to his private detective business, Capital Investigations, Wheeler is also, according to his LinkedIn, the CEO and founder of the Global Food Defense Institute. ("Food defense," per the website of the FDA, focuses on "the risk of criminal or terrorist actions on the food supply.")
