Anthony Fauci, FDA commissioner Stephen Hahn, CDC director Robert Redfield, and coronavirus testing coordinator Brett Giroir will testify via videoconference before the Senate Health, Education, Labor and Pensions Committee on Tuesday, Sen. Lamar Alexander (R-Tenn.) announced Sunday.

Why it matters: Fauci, Redfield and Hahn are all self-quarantining after coming in "low risk" contact with a White House staffer who tested positive for the virus.

The big picture: This will be the first time Trump administration health officials will testify about the federal government's response to the pandemic since the White House announced it would block members of the coronavirus task force from testifying during the month May.

  • In March, Fauci testified that the current system of making coronavirus testing available in the U.S. was not set up in a way that it needed it to be, calling it a "failing."
  • President Trump has since dismissed attempts to conduct oversight over the administration's coronavirus response, even claiming that the House of Representatives is "a bunch of Trump haters."

The White House coronavirus task force will examine more closely just how much SARS-CoV-2 might be transmitted via aerosols, and not just from droplets, NIAID director Anthony Fauci said Wednesday at an online forum sponsored by Harvard T.H. Chan School of Public Health.

Why it matters: The longer the coronavirus can remain infectious in the air, the more likely it can infect people, particularly indoors — leading to the possible need to alter air filtration and circulation within buildings.

Fauci calls U.S. coronavirus testing delays "totally unacceptable"

NIAID director Anthony Fauci told CNN's chief medical correspondent Sanjay Gupta on Wednesday that it is "totally unacceptable" that Gupta was unable to test a patient for the coronavirus before operating on them.

Why it matters: Mass delays in coronavirus test results across the U.S. have thwarted mitigation efforts recommended by public health experts, per the New York Times. In absence of a federal plan, a bipartisan group of governors on Tuesday proposed one of the country's first interstate testing strategies.

Rep. Rodney Davis (R-Ill.) announced on Wednesday that he has tested positive for the coronavirus.

Why it matters: Davis, the top Republican on the House Administration Committee, said he has taken precautions against the virus, such as twice-daily temperature checks. He spoke to Republicans about staying safe after Rep. Louie Gohmert (R-Tex.) recently tested positive for the virus and spoke out against wearing face masks, Politico notes.
