After being sworn in by Sen. Chuck Grassley (R-Iowa) on Thursday, Supreme Court Chief Justice John Roberts administered an oath for all senators to deliver "impartial justice" in the impeachment trial of President Trump.

Why it matters: The ceremony kicks off a period in which senators will not be permitted to speak to each other or bring electronic devices onto the Senate floor.

  • Several Republican senators, including Majority Leader Mitch McConnell (R-Ky.) and Lindsey Graham (R-S.C.), have sparked controversy by stating that they will not be impartial jurors.
  • McConnell will recess the substantive part of the trial — opening arguments and the Q&A period — until Tuesday in order to give House managers and Trump's defense team a few days to prepare.

What they're saying: The oath, which dates back to the 1700s, reads: “I solemnly swear that in all things appertaining to the trial of the impeachment of Donald John Trump, president of the United States, now pending, I will do impartial justice according to the Constitution and laws: So help me God."

A group of 239 scientists in 32 countries is calling for the World Health Organization to revise its recommendations to account for airborne transmission as a significant factor in how the coronavirus spreads, the New York Times reports.

The big picture: The WHO has said the virus mainly spreads via large respiratory droplets that fall to the ground once they've been discharged in coughs and sneezes. But the scientists say evidence shows the virus can spread from smaller particles that linger in air indoors.
