All four U.S. broadcast networks will carry Donald Trump's live primetime address at 9 p.m. ET on Wednesday after he posted on Truth Social that he would speak from the White House.Networks said the announcement arrived with roughly six hours' notice, forcing schedulers to change plans and interrupt major season finales and holiday specials including CBS's Season 49 finale of Survivor and Fox's season-four finale of The Floor.White House press secretary Karoline Leavitt said Trump will use the speech to outline his accomplishments and plans for the next three years, and viewers complained online with some urging networks not to carry the address and others criticizing the president for using prime entertainment slots.
