Colbert Become Persona Non Grata to Congress

Looks like Stephen Colbert jumped the shark with his in-character testimony in Congress last week:

Members of Congress have been fooled time after time after time by Stephen Colbert, and after last week’s mockery, they have a message for the satirist who makes a living lampooning them: Colbert, you’re dead to us.

Colbert’s act had steadily been losing cachet on Capitol Hill, but his spoof testimony merely accelerated a pending divorce.

Lawmakers and their aides are repeatedly turning down requests for “The Colbert Report,” political advisers are suggesting members avoid Colbert like the plague and the infamous “Better Know a District” segment that put Colbert on the map on Capitol Hill appears to be dying out.

In other industries this would be called "ruining the brand".
