UPDATE! Remember: Speaker Pelosi REQUESTED that Trump Postpone the SOTU

She didn't tell him to cancel it.

All of the reaction from the other side has ACTED like she cancelled it. She has many ways to respond to their foot-stomping. They have played their hand. She has yet to respond to it.

I suspect she will do something interesting. We shall soon see.

AND SHE JUST RESPONDED!
Here it is: House will not consider resolution to authorize SOTU. When you can grow up, we can talk about an agreed upon date (paraphrased)
