Jake Tapper pins Robert Gibbs like a butterfly.

As the guest host on Sunday’s “This Morning with George Stephanopoulos” show, Jake Tapper tried to school Robert Gibbs on the meaning of the word “transparency,” as well as the difference between public “voting” and secret “negotiations” on health care reform, but Gibbs was having none of it.

By his own admission, Tapper — “in the spirit of the Christmas season” — gave Gibbs more than one chance to explain away why President Obama is choosing to ignore his campaign pledge to “‘have the negotiations televised on C-SPAN, so the people can see who is making arguments on behalf of their constituents and who is making arguments on behalf of the drug companies or the insurance companies.'” And even though Tapper used a wry restraint throughout his post about the verbal exchange, the title for the article says it all:

Gibbs Passes On One Last Chance to Make Health

Care Negotiations Transparent

Seeing at least one member of the mainstream media bring attention to the crucial intersection between Obama’s campaign promises and the health care mess? . . . Encouraging.

Watching him make fun of Gibbs in the process? . . . A late Christmas present.
