More than 200 mayors signed onto a letter to Senate Majority Leader Mitch McConnell (R-Ky.) and Minority Leader Chuck Schumer (D-N.Y.) on Thursday urging them to cancel the Senate's August recess to address gun control following last weekend's mass shootings in El Paso and Dayton, Ohio.

"Already in 2019, there have been over 250 mass shootings. The tragic events in El Paso and Dayton this weekend are just the latest reminders that our nation can no longer wait for our federal government to take the actions necessary to prevent people who should not have access to firearms from being able to purchase them."

The big picture: The mayors of Dayton, El Paso, Orlando, Pittsburgh, Parkland, Fla., Annapolis, Md. and other cities that have been the site of mass shootings in recent years are among the 214 calling for the Senate to vote on two background check bills that have already passed the House.

  • H.R. 8 would require background checks for all firearm sales, including those sold at gun shows and online.
  • H.R. 1112, spearheaded by Rep. Jim Clyburn (D-S.C.), who represents Charleston, would "extend the background check review period deadline from three to 10 business days."

The big picture: The Justice Department, the Federal Trade Commission and the states have multiple investigations of monopolistic behavior underway targeting Facebook and Google, with other giants like Amazon and Apple also facing rising scrutiny. Many observers expect a lawsuit against Google to land this summer.

John Roberts' long game

Supreme Court Chief Justice John Roberts is not the revolutionary that conservative activists want him to be.

He moves slower than they want, sides with liberals more than they want, and trims his sails in ways they find maddening. But he is still deeply and unmistakably conservative, pulling the law to the right — at his own pace and in his own image.

The U.S.' new default coronavirus strategy: herd immunity

Illustration: Aïda Amer/Axios

By letting the coronavirus surge through the population with only minimal social distancing measures in place, the U.S. has accidentally become the world’s largest experiment in herd immunity.

Why it matters: Letting the virus spread while minimizing human loss is doable, in theory. But it requires very strict protections for vulnerable people, almost none of which the U.S. has established.
