When news broke that S&P downgraded the United States economy, Fox Business News’ Liz Claman immediately reached Warren Buffett for comment. The billionaire expressed disappointment and confusion that S&P made the decision to mark down the U.S. from AAA to AA+.

Fox Business anchor Liz Claman was working the phones–talking to Warren Buffett–when she looked up and saw the Dow heading down. “At that point we were down a couple of hundred points,” Claman told Mediaite. “I rushed down to the New York Stock Exchange to find that all the traders were pretty concerned, but calm–saying it didn’t feel like panic selling. It was just an ugly, slow sell-off that went to the worst levels by the end of the session.”

FBN correspondent Charlie Gasparino tried an ambush interview with Treasury Secretary Tim Geithner in an odd place – the building Fox Business is located in.

Geithner didn’t really want to talk, but that didn’t stop Gasparino from trying – and throwing in some shots at his old employer, CNBC (or – “Brand X” as he called them).

We’ve written before about the connection between sports and business at Fox Business Network, and this week has been no exception.

But besides interviews and segments, FOX used a golden marketing opportunity in the minutes before the MLB All-Star game to promote its new FBN stars.

One of the first anchors from another network to join the young Fox Business Network in 2007 was Liz Claman, who came over from CNBC. This week the Los Angeles Times profiled the star at FBN, who revealed a bit about her “tree-hugging, West Coast, free-market, liberal Jew from L.A.” background.

Liz Claman just returned from her first trip to Davos, Switzerland, covering the 40th World Economic Forum for Fox Business Network. The former CNBC anchor, and one of the biggest stars at the new FOX-run business network, interviewed industry leaders including Bill Gates, IMAX CEO Rich Gelfond, NYSE CEO Duncan Niederauer and even former Pres. Bill Clinton. She also moderated a panel called “Renewable Energy as an Engine for Economic Growth” which featured author Tom Friedman, among others. Now back in America, Claman is the latest media member in our 5QQ – Five Quick Questions series.

The man who preceded Jeff Zucker as head of NBCU, Bob Wright, was on Fox Business Network yesterday in an interview focused on Autism. But FBN anchor Liz Claman (a former NBCU employee herself) also asked about the potential sale of the company, Jay Leno‘s lagging ratings and more.
