There is growing tension within the ranks at Fox News over the Glenn Beck Clown Show: Howard Kurtz - The Beck Factor at Fox: Staffers say comments taint their work. (Ya think?)

Fox staffers note that veteran producer Gresham Striegel left the network after clashing with Beck and say the host has surrounded himself with loyalists from Mercury, some of whom remain on that company’s payroll. (Striegel did not respond to a request for comment.) When Fox covers breaking news during Beck’s hour, some journalists say, they are flooded with angry e-mail from viewers about the preemption.

Friction between opinionated cable personalities and journalists has also flared occasionally at MSNBC. But Beck has caused such anguish at Fox that some of its journalists celebrated the failure of last week’s interview with embattled ex-congressman Eric Massa, which Beck pronounced a waste of time.

Love him or hate him, Beck is a talented, often funny broadcaster, a recovering alcoholic with an unabashedly emotional style. Yet even that has caused grousing. Some staffers say they have watched rehearsals, on internal monitors, in which Beck has teared up or paused at the same moments as he later did during the show. Asked about this, Balfe responded sharply: “Glenn reacts the same way to issues whether he knows people are watching or not, and is proud to show his emotions, unlike the cowardly, two-faced critics who hide behind anonymity.”
