President Trump announced that he will address the nation on Tuesday at 9 pm ET regarding the ongoing partial government shutdown before a visit to the U.S.-Mexico border on Thursday that White House press secretary Sarah Sanders said will see him "meet with those on the frontlines of the national security and humanitarian crisis."

Background: Trump said he would focus on "the Humanitarian and National Security crisis on our Southern Border" in his prime-time speech, which was first reported by the New York Times. Trump's visit to the border will come on the 20th day of the shutdown, should it continue, which is in a stalemate over his demand that congressional Democrats vote to fund a wall — now a steel barrier — along the border.
