The Democratic National Committee has accused the MSNBC cable channel of having "a pretty big double standard" regarding its “confusing policy” of forbidding some anchors from attending political fundraising events while others are allowed to speak at similar programs, according to a letter written to Phil Griffin, president of the liberal television network.

Mo Elleithee, the DNC's communications director, indicated that channel executives prevented Ed Schultz -- host of the weekday afternoon program The Ed Show – from appearing at a Democratic Unity Dinner in Broward County, Fla., on March 15, while Joe Scarborough, a co-host of the weekday Morning Joe program, is slated to give the keynote address at next month's Cheshire County Republican Lincoln Day Dinner in New Hampshire.
