I cannot see how Nancy Pelosi can legally block a State of the Union Address – according to Article II, Section 3, the President is required by law to deliver the SOTU:
“He shall from time to time give to the Congress Information of the State of the Union…he may, on extraordinary Occasions, convene both Houses, or either of them…as he shall think proper”.
And: [He] shall take Care that the Laws be faithfully executed…” – thus it appears that by law, President Trump cannot permit Nancy Pelosi to block the SOTU…
