For the backstory, see Greg Sargent.

Did he really hold up a dead mouse on the floor of the House? I can't tell what's in that little bag he shook around there.

Late Update: Price's flack tells Greg Sargent, "It was a toy mouse, from a pet store."

I can just see some well-scrubbed young GOP aide, new to Washington, being sent out to a pet store to find a toy mouse to use as a prop. Heady day for that kid.
