https://www.cnn.com/2019/01/23/politics/donald-trump-nancy-pelosi-state-of-the-union/index.html Trump doesn't respect women or the word "no". Especially when combined. Pelosi responded to Trump's taunt. Reporting from CNN suggests that administration officials planned Trump's letter as an effort to force Pelosi's hand. So now we will wait and see the next reaction - whether Trump will delay the speech or deliver the speech at another venue. As I have discussed multiple times at this point, it will be rather interesting to see how much control Trump can exercise over the crowd which attends this speech. It is a government event, not a campaign event, and as such, the First Amendment prevents the government from disallowing individuals based purely on their political leanings. I, for one, look forward to a crowd which is mostly filled with people who disapprove of Trump (much like his national disapproval rating).
