Former Ohio Gov. John Kasich is joining CNN as a contributor, serving as an analyst across the network, CNN Worldwide President Jeff Zucker told his team Tuesday morning.

The big picture: The 66-year-old Kasich, a former U.S. House member, has been one of cable news' most in-demand Republican voices as the party's only likely primary challenger to President Trump. John Weaver, a longtime Kasich adviser, told Axios: "The governor has strong insights to help guide conversations in our country in a positive direction and this new partnership with CNN gives him a great platform to do so."

Why it matters: Cyberattacks by Russian intelligence and Russian-speaking criminal groups, as well as the Kremlin's attempted assassination and jailing of Navalny, are among the topics President Biden is expected to raise at his Geneva summit with Putin on Wednesday.

Why it matters: The study of 29,960 participants in the U.S. and Mexico found the shot was safe and highly effective, paving the way for the FDA to clear a 4th vaccine for emergency use by the end of the year.
