From CNN’s Reliable Sources with Oliver Darcy:

A split-screen is about to play out this week.

On Monday night, former Vice President Mike Pence kicked off his book tour, appearing for a candid sit-down with ABC News’ David Muir in which he forcefully denounced his former boss, ex-President Donald Trump. Meanwhile, Trump is set to announce on Tuesday night from his Mar-a-Lago Club in Palm Beach that he will run for president in 2024.

It’s an unprecedented situation unfolding on television screens: A former president announcing another bid for the White House as his former vice president criticizes him on a high-profile national media tour.
