Vice President Mike Pence and Senator Kamala Harris are set to square off this evening in a vice-presidential debate, despite concerns that Pence may be infected with the coronavirus. Pence’s team says the vice president continues to test negative, and claims he doesn’t need to quarantine since his recent contacts with the president and other infected government officials weren’t “close contact” as defined by the CDC.

On Tuesday, Pence’s team dropped its opposition to having a plexiglass barrier erected next to him at tonight’s debate. Earlier this week, Pence’s top aide, Katie Miller, mocked Kamala Harris for trying to build a “fortress” around herself by demanding a plexiglass shield. Katie Miller’s husband, Stephen Miller, has since tested positive for the coronavirus.

Meanwhile, President Trump tweeted from the White House Tuesday that he looks forward to debating Joe Biden next Thursday in Miami — even though he’s still sick with COVID-19 and likely highly infectious. On Tuesday, Joe Biden said he’ll debate Trump, but only if medical experts say the president is no longer contagious.

Joe Biden: “I think if he still has COVID, we shouldn’t have a debate.”
