During an interview with Biden's running mate, Sen. Kamala Harris, Maddow asked whether she was “as mad as everybody else” about the Trump town hall. NBC said it agreed to set up the dueling town hall after Trump was administered a coronavirus test Tuesday by the National Institutes of Health. Trump's town hall on NBC is scheduled for an hour. An estimated 6.7 million people saw Biden at an NBC News-sponsored town hall last week. Trump's ABC town hall with Stephanopoulos on Sept. 15 was seen by 3.8 million people, Nielsen said.

Biden's campaign then suggested the event be delayed a week until Oct. 22, which is when the third and final debate was already scheduled. Next, Trump countered again, agreeing to a debate on Oct. 22 — but only if face to face — and asking that a third contest be added on Oct. 29, just before the election. The Oct. 22 debate in Nashville, Tennessee, is scheduled to feature a format similar to the first. Biden’s campaign has suggested that it be modified to the “town meeting” format, though the Trump campaign has not weighed in. As he campaigned in Arizona, Biden said he would indeed attend the Oct. 22 debate.

Chris Christie, seen in an AP photo with his arm around another guest while chatting up several face to face, announced his positive virus test this weekend.

White House officials said they began learning of Hicks’ positive test after Trump boarded Marine One to start his journey to New Jersey. Despite the abject failure to keep the president protected from the virus, White House officials defended their current protocols as well thought out. And masks still won't be required on the White House grounds for all West Wing employees.

WASHINGTON The University of Notre Dame has become the second university to withdraw as the host of one of this fall's three scheduled presidential debates amid the coronavirus pandemic. The university was set to host the inaugural face-off between President Donald Trump and former Vice President Joe Biden on Sept. 29. The first debate will now be hosted by Case Western Reserve University and Cleveland Clinic in Cleveland, the nonpartisan Commission on Presidential Debates announced Monday. The commission has selected Cleveland Clinic as its health adviser for all three presidential debates and the one scheduled vice presidential debate. John Jenkins said the university made this difficult decision because the necessary health precautions would have greatly diminished the educational value of hosting the debate on our campus.The University of Michigan was scheduled to host the second presidential debate but withdrew last month.
