Dr Birx shared a personal story about her granddaughter’s current high fever and her inability to visit. Earlier, Trump accidentally referred to her “grandson”.

“I’m sure it’s roseola or something,” Birx says of her 10-month-old granddaughter’s high fever.

She doubts it’s coronavirus because her family is self-isolating.

“No one is allowed into that house or out of that house because there’s too much precious cargo inside,” Birx says https://t.co/zvWlrulgbf

More details from the Guardian’s Sam Levine on the Wisconsin election:

The US supreme court ruled 5-4 that Wisconsin voters have to have their mail-in ballots postmarked by 7 April, election day, in order to have them counted in the state’s closely watched election. The deadline for election officials to receive the ballot is 13 April. The decision, which came shortly after the state supreme court ordered the election to move forward on Tuesday, ends days of legal fighting over the deadline for receiving absentee ballots in the state.

While I do not doubt the good faith of my colleagues, the court’s order, I fear, will result in massive disenfranchisement. A voter cannot deliver for postmarking a ballot she has not received. The question here is whether tens of thousands of Wisconsin citizens can vote safely in the midst of a pandemic.”
