House GOP leadership was not pleased when Bachmann decided to freelance, and in the days before the speech, Bachmann herself sought to recast the rebuttal, apparently hoping to reverse the impression that it was a Tea Party alternative to the official Republican response.
However, Boehner is not publicly discouraging members from responding to the State of the Union in any number of ways. "I think all members, House and Senate, Democrat and Republican, responded to the President's speech last nights in a lot of different forms," he said. The more the merrier."
Presumably, though, he's not suggesting more of this.
