With the federal government issuing massive amounts of debt and the Federal Reserve purchasing it in the name of keeping interest rates down, questions have arisen about impact on the U.S. dollar.

On June 2, CNBC's "Power Lunch," aired a clip of the network's chief economics reporter, Steve Liesman interviewing Secretary of the Treasury Timothy Geithner. Geithner claimed the Federal Reserve wasn't monetizing the debt the government was accruing. Following that clip, CNBC's Chicago Mercantile Exchange floor reporter Rick Santelli, famous for inspiring the anti-tax-and-spending tea parties, questioned Geithner's denial of debt monetization.

"Well, you know the first part of that question was economists are worried about quantitative easing - are we monetizing?" Santelli said. "And his answer was no, we have a strong independent central bank. Now the latter may be true but it certainly isn't an answer to the question and I put forth, and I'd like feedback everybody - that quantitative easing can't exist without the monetization process. We issue debt; we print the money to buy it. That is monetizing. I can't believe that was his answer."

CNBC has been a hotbed for commentary - both left and right, from Rick Santelli's call for a tea party on the floor of the Chicago Mercantile Exchange to the hiring of former Democratic Committee Chairman Howard Dean as a CNBC contributor.      

This time, one of the hosts on CNBC's March 26 "Power Lunch" dropped an expletive during President Barack Obama's online town hall meeting as the network broke away from their coverage (h/t Breitbart.tv):

PRESIDENT BARACK OBAMA: One last point I want to make and I know I'm not suppose to talk this long ...

UNIDENTIFIED CNBC HOST: Bull****.

It's not often someone in the media challenges the liberal point-of-view - especially on the issue of taxes when they become a means to redistribute income.

CNBC "Squawk Box" fill-in co-host Michelle Caruso-Cabrera wasn't afraid to buck the trend and challenge Democratic presidential nominee Sen. Barack Obama's senior economic adviser Austan Goolsbee.

Goolsbee appeared on the August 14 "Squawk Box" to defend an op-ed he wrote for the August 14 Wall Street Journal outlining Obama's tax plan. Caruso-Cabrera invoked the name of Milton Friedman, an economist who was a primary defender of free markets throughout the 20th century. Ironically, Friedman taught at the University of Chicago, where Goolsbee is a faculty member.

"WWMD, Austin - what would Milton do? Remember that," Caruso-Cabrera said. "Remember your roots - what got you to where you are."
