CBS viewers should not be surprised when the season 49 finale of Survivor is interrupted by President Donald Trump. CBS News will air a special report on Wednesday, December 17, where Trump, 79, is expected to share an update with the public from the White House at 9 p.m. ET. CBS News' Norah O'Donnell will anchor reporting from the White House with appearances by chief White House correspondent Nancy Cordes. Trump's message is expected to cause a delay for the Survivor finale, which is scheduled to start at 8 p.m. ET.
