You can’t impeach members of Congress—it’s only for executive and judicial officers. They could expel her, but that requires 2/3 of the House. Removing her as Speaker requires only a majority, and functionally, requires only a majority of the Democratic caucus.
lol. It’s all hooray for Bachmann, post some pretty pictures, while everyone ignores the fact that what she is calling for is unconstitutional. How’s that for irony?
