Horrible thought, what if the Demoncrats have something bad planned for the SOTU tonight. First they defunded President Trump's protection agents, no paychecks? And now they aren't going to be in attendance. Read the last Sentence of the paragraph below, regarding History, Evolution and Practice of the SOTU. Well, I am a conspiracy theorist after all, my mind goes there sometimes.

"As the address is now broadcast and webcast to a "prime time" national and international audience, it serves several functions: as a report to Congress and the nation on national conditions; as a platform to announce and rally support for the President's legislative agenda for the coming year; and as a unique opportunity for the chief executive to convey a vision for the nation to Congress and the American people. To ensure continuity of government, one Cabinet officer (and in more recent years, selected Members of Congress) are absent from the Capitol during the address."
