From Holden:

Dan Froomkin leads us to this report in the Rocky Mountain News indicating that the man who impersonated a federal agent and threw three citizens out of a taxpayer-funded town hall meeting in Denver may hvae been a White House staff member.

[T]he head of the Denver office of the Secret Service is now saying he never described the man in question as a Republican party staffer.

“Instead, he said the man was ‘a member of the Republican staff host committee.’. . . .

“Rachael Sunbarger, spokeswoman for the Colorado Republican Party, said, ‘The White House is the host committee.’ “
