If she denies the invite, there should never be another sotu by a Democrat president in a GOP house.
If she denies him he will address the senate and the the republican house and the democrats will have displayed yet again an historic level of contempt for America.
State of the Union is a Constitutional requirement.
I encourage her to rescind the invitation (so she can look smaller)....and then DJT can present the SOTU on TV, or perhaps in the senate with no reps present.
